Two are state senators. One is a county prosecutor. One is a township trustee. One is an architect.

The 10 Republicans who hope to succeed U.S. Rep. Pat Tiberi (R-Genoa Township) run a wild gamut of experience and qualifications. By running in the May 8 primary election, each hopes to win the 12th Congressional District seat that has been in Republican hands since John Kasich won it in 1982.

Tiberi has represented the 12th District, which stretches from northern parts of Franklin County to take in Delaware and Morrow counties and the Mansfield area and then east to cover all of Licking County and part of Muskingum County, for most of the past two decades.

But he stepped down in January to take a job at the Ohio Business Roundtable, one year before his term expired.

Federal law requires a special election to fill an interim seat in such cases.

As a result, two separate primaries for both major parties are necessary May 8: one for the Aug. 7 special election to determine who serves Tiberi's final five months in office and the other to determine who will compete Nov. 6 for a full two-year term starting in January 2019.

Here are the Republican candidates for the 12th District primaries:

John Adams

Adams, 72, of Galloway unsuccessfully challenged Rep. Joyce Beatty (D-Jefferson Township) in 2014 and 2016, losing the GOP primary in 2012. Before that he served two terms on the Portsmouth City Council and served on the Portsmouth school board.

As a candidate, he said he calls for repealing "every aspect of Obamacare," moving health care to the private sector and introducing a bill to have "every dime" that Americans were fined because of Obamacare returned. He said he supports Trump's tariffs on imported steel, arming teachers to minimize school shootings and building a wall along the southern border of the United States.

Unlike other Republicans, however, he opposes abolishing the Consumer Financial Protection Bureau, a government watchdog that oversees banks and credit card companies. He says Republicans "need to take the lead" in protecting consumers.

Kevin Bacon

Bacon, 46, of Westerville has served as an attorney, a township trustee, a state representative and now a state senator, saying he has dedicated his life to public service. He said one of his top priorities would be addressing the heroin and opioid epidemic with a comprehensive strategy that attacks the problem on both the supply and demand sides.

In a questionnaire on his stances, Bacon repeatedly mentioned that he supports the agenda of President Donald Trump, saying Trump "ran on a platform that Ohioans support, and I intend to hold true to that." He backs the repeal and replacement of the Affordable Care Act, tariffs on imported steel as part of a larger negotiation with China, and Trump's immigration agenda, including the building of a border wall, "if we can do it for a price that makes sense."

He said he proudly supports the Second Amendment. He calls for the nation to address its mental-health crisis and "stop demonizing the millions of lawful gun owners in this country that use their firearm legally."

Troy Balderson

Balderson, 56, of Zanesville is a state senator and had served in the Ohio House. A family farmer and former businessman, he describes himself as "the only candidate in this race who has signed both the back and the front of a paycheck."

He said he is focused heavily on economic issues including spending, taxes and jobs. He said our national debt "is completely unsustainable" and he has "very serious concerns" with recently imposed tariffs on imported steel and aluminum.

"I support free trade as long as it's fair," he said, but acknowledges that the nation "has consistently been ripped off by unfair trade deals, particularly by China."

Balderson said that while the mass shootings in the nation have been unimaginable, he does not believe banning or regulating guns will end gun violence, and he'd prefer to use federal dollars to identify and treat those with mental-health problems. Although he supports arming teachers, "that decision should be left up to individual school districts -- not decided as blanket federal policy for the entire nation."

Lawrence Cohen

Cohen, 49, a New Albany attorney and accountant, opposes tariffs to steel and aluminum imports, saying the focus instead should be on 21st century jobs and better training opportunities for displaced and young workers.

"We do not need to be training steelworkers, switchboard operators or elevator operators but web developers, cybercrime specialists, robot technicians, construction workers and electricians," he said.

Unlike other GOP candidates, Cohen calls for a short-term expansion of Medicaid while Congress writes laws to fix what he calls a "bloated, over-regulated and outdated insurance model," saying "if allowed to operate efficiently, the market can provide all Americans access to quality and affordable health care and prescription drugs."

He is rare among Republicans by saying he does not want U.S. taxpayers to pay for a border wall.

"I do not support paying billions for a wall while veterans are homeless and people are dying because they can't afford health care," he said.

Jon Halverstadt

Halverstadt, 34, a real-estate agent and Army veteran from Worthington who was deployed to Iraq and Afghanistan, identifies the opioid crisis and infrastructure as key issues. He calls for another exit along Interstate 71 north of Interstate 270.

He said he supports repealing or overhauling the Affordable Care Act and argues that while Medicare and Social Security should remain unchanged for those who are retired or about to retire, "these programs should change for people my age."

He cautions against a wholesale end to the North America Free Trade Agreement, saying it would cost farmers billions in revenue with Mexico and Canada.

Halverstadt said that while he does not want to deport children brought to this country illegally who are here under DACA, he does support comprehensive immigration reform.

"We should first secure the border and then reform the guest worker program to ensure we know who is here," he said.

Tim Kane

Kane, 49, of Dublin, who moved back to the district after serving as an economist at the Hoover Institution, is an Air Force veteran raised in central Ohio. He argues that he understands national and international issues better than anyone else in the race: "I will make Washington work for Ohio."

By Kane's definition, that means encouraging entrepreneurship in central Ohio; making last year's tax bill permanent for individuals and some small businesses; and eliminating the Affordable Care Act to "unleash free-market forces in the health-care space."

Kane said he supports a balanced budget amendment to the U.S. Constitution and argues that government expansion over recent decades has slowed economic growth. "Limited government is the answer," he said.

He said the focus on mass shootings is caused in part by a "sensational media culture," and violence and homicides have in fact dropped steadily in recent decades. He supports the right of local school districts to decide whether to allow teachers to be armed, "but strongly believe my own children will be safer if their teachers are empowered rather than disarmed."

Melanie Leneghan

Leneghan, 53, of Liberty Township is emphasizing her conservative credentials as she makes her first bid for Congress. She describes herself as a wife and mother who helped defeat a tax increase as township trustee, and touts her endorsement by Rep. Jim Jordan, as well as by a series of conservative groups, describing herself as "a Christian Conservative, Constitutional Conservative and Trump Conservative," adding, "I share the values of our district."

She said the major issue facing the nation is the people's lack of power. "I'm running to take the people's power back to Washington."

After reciting her priorities, she says, "Hold me to them. The People: Respect Them! Our Military and First Responders: Support Them! Life: Protect It! The Constitution: Defend It! Excessive Spending: Stop It! Obamacare; End It! The Wall: Build It! The Swamp: Drain It!"

Pat Manley

Manley, 62, a Clintonville architect, businessman and college instructor, identifies well-paying jobs as his top issue, saying while there are plenty of entry-level jobs in the district, there aren't enough high-paid, skilled jobs. "Good-paying career jobs make the other problems become easier to solve."

Manley, a leukemia survivor, said the only way to make health care affordable is to create a market-based system where competition is available across state lines and those with pre-existing conditions have equal access to care. He said while he does not support Medicaid expansion, "with good jobs, we can reduce the Medicaid rolls to a manageable level."

He said he supports the idea of having at least two trained and armed protectors in every school. He said he also would fight for smaller schools where every teacher and administrator knows each child.

"Too many children fall through the cracks, getting lost and ignored in large schools."

Carol O'Brien

The Delaware County prosecutor, O'Brien, 59, said one of her key priorities if elected would be addressing the opioid epidemic.

She said she supports a multilayered approach that includes securing the borders, educating people about the dangers of opioids and an effective treatment program. She said the epidemic has made it difficult for employers to find employees who can pass a drug test. "The opioid epidemic is destroying an entire generation of workers," so curbing the crisis will help ensure a stable workforce.

She supports the tariff on steel and aluminum imposed by Trump but said she'd like to see it narrowed. O'Brien supports arming teachers if they are properly trained and vetted.

"Children and educators deserve the same protection that is afforded legislators whose buildings are equipped with metal detectors and armed law enforcement," she said.

Mick Shoemaker Jr.

Shoemaker, 61, of Sunbury said he wants to go to Washington "to be a disruptor. ... I want to upend the system and make government more responsive to the people."

He identified the biggest problem in the district as "the breakdown of the American family" and said "gay marriage and LGBT rights proponents have undermined the pre-eminence of marriage to the detriment of society."

He supports reform of Social Security and Medicare/Medicaid: "If any officeholder or candidate for office says that 'entitlements' can continue as presently constituted, they are lying!"
