GOP candidates Mitt Romney and Rick Santorum devoted most of their campaigning to the state in the last day before the 10-state primary voting. Romney is looking for a decisive victory while Santorum hopes to regain momentum in his chase.

While Santorum took aim at Romney, the former Masscahusetts governor didn’t mention Santorum’s name a single time. Instead he criticized President Obama for what Romney called a failed record on job creation.

Former House Speaker Newt Gingrich also is hoping to pick up some delegates, while banking his comeback hopes on winning his home state of Georgia.

Ohio primary voters have plenty of other choices to make, including an unusual match of two Democratic U.S. House members pushed together in congressional redistricting, as well as primaries for other House races, the U.S. Senate, seats in the state Legislature, and for the Ohio Supreme Court.

In Franklin County, voters are casting ballots on township services, library and school levies, liquor issues, and other initiatives.

Polls are open until 7:30 this evening.

A major reason for that is that about a third of likely GOP voters say they could still changed their mind before heading to the polls.

Throughout the GOP presidential campaign, in several states, polls have shown big numbers of likely Republican voters were leaning toward a candidate, but also saying they could still change their minds before they cast their ballots. Charley Lough of Vermillion is one of them.

“Right now I’m torn. I see good things in all of them and bad things in all of them, and I can’t decide which one for sure I really want. I’m just, I just don’t feel like any of the candidates are strong,” says Vermillion.

Lough was considering Rick Santorum, but now isn’t sure who he’ll vote for. Monica Rus of Euclid favored Santorum too at one point, and is now looking at Mitt Romney. But she’s also uncertain.

“As a middle-classer – well, lower than middle class – neither one really seemed to be on the same level as the people in my neighborhood, my family,” says Rus. ”

“One seemed a little bit rich; the other one, I’m not sure of.”

And the indecision isn’t isolated to voters. Bill Johnson is a Republican Party insider – he’s an elected member of the Cuyahoga County Central Committee. He turned to Newt Gingrich when Herman Cain dropped out of the race, then looked to Santorum but hasn’t liked some of his recent remarks about religion and government. So now he doesn’t know how he’ll vote.

“I’m not really sure at this point. I really would hope that the convention will draft another candidate or that we’ll have another candidate enter the race at the last minute,” Johnson says.

And many Republican voters are frustrated. Lenan Empey is originally from Massachusetts, and now lives on the west side of Columbus. And she calls herself a proud member of the GOP.

“How could the Republican Party produce four candidates that absolutely, to me, are – I’m just blown away at how bad they all seem to me at being representative of the Republican Party that I fell in love with,” Empey says.

These four voters say they want to hear more about jobs and the economy. Charley Lough wants the candidates to talk about how to reduce the size of government. Lenan Empey says she agrees but wants a more moderate approach.

Monica Rus says she’s also concerned about health care and taxes. And Johnson says when the candidates talk about other issues, they’re diverting attention away from what voters really want to hear about.

Ohio Republican Party chair Kevin DeWine has heard many of these comments and complaints from his voters. DeWine, who supports Romney, says the candidates need to keep working on how they present their messages to voters.

“My advice to candidates has been and will continue to be to tell us as the voters what do you stand for, what do you plan to do? Because it’s not just good enough to say that your opponent doesn’t deserve to be elected.”

Quinnipiac pollster Peter Brown backs that up, saying he thinks many voters are waffling because they simply don’t know the candidates – Romney’s the best known because he ran just four years ago, and Brown says he’s probably the best positioned to come out the winner in Ohio because he has the most money to spend to reach voters.

“Money matters, and TV commercials move numbers,” Brown says.

Voters and pundits have long speculated on what the race might be like if there were other well-known Republican figures in it. Charley Lough wishes he could be voting for former Secretary of State Condoleeza Rice. Monica Rus says she misses George W. Bush. And Bill Johnson is hoping the party can draft President Bush’s brother Jeb Bush to join the race.

Early voting starts in all 88 counties Tuesday and runs through March 2, says Secretary of State spokesman Matt McClellan.

“Voters have 35 days beginning today to vote. They can do it by mail, they can do it in person, or they can wait and they can go on election day.”

All four of the Republican candidates for president on the ballot in Florida will be on Ohio’s ballot – there’s also a 6 way contest for the GOP nomination for US Senate. On the Democratic side, there’s a primary for Ohio Supreme Court. And both parties have primary races in Congressional and Statehouse races throughout the state. There are 9 bond issues and 280 tax issues statewide – 85 of those are school levies. Would be voters have until February 6 to register.

A new poll from Quinnipiac University says Cain now leads all Republican contenders in Ohio with 28 support…that’s five points higher than Mitt Romney and a 24 point lead over Texas Governor Rick Perry.

The same poll gives President Obama a lead over Cain, Romney and Perry.
