MCCRACKEN COUNTY, Ky. — There are big differences between Republicans and Democrats but Kentucky primary election results reveal there are some similarities with voters in both parties.

Despite having no opposition, 42 percent of Kentucky Democrats refused to vote for President Obama, voting "uncomitted" instead.

Meanwhile, a third of Republicans voted against GOP frontrunner Mitt Romney.

Murray State University political science professor Dr. Ihsan Alkhatib said it's an indication of just how unhappy many voters are, to go so far as to vote "uncommitted" or vote for someone who can't possibly win.

He said out of all the voters, both Republican and Democratic, it's likely the conservative population who are the most unhappy with this year's ballot.

Alkhatib said this year's primary reveals a lot.

"This election is not exciting for either the Republicans or the Democrats," he said.

Alkhatib believes conservatives are concerned about where President Obama was born, despite the release of his birth certificate. He also said some still doubt President Obama's Christianity, buying into the now-debunked idea the president is a Muslim.

But voters also don't like that Romney is a Mormon.

"On election day, it's going to be the guy who's not Christian or the guy who's Muslim," Alkhatib said of some voters attitudes.

Alkhatib's students don't worry so much about the candidate's faith but the students we spoke with weren't overly anxious to vote, either.

The include Purple Heart recipient Aaron Curry, who served in Iraq and Afghanistan.

"If I had to pick between Obama and Romney, I'd probably pick Obama just because of the decisive action he took against Osama bin Laden," Curry said.

But Curry said he might not even vote.

Classmate Ken Hopkins did vote in the primary. He's a registered Republican, voted for Romney, but said that's only because other Republicans didn't stand a chance.

In his opinion, Romney isn't conservative enough. He voted with one hand on the ballot the other on his nose.

"It didn't make me comfortable to be quite honest with it," Hopkins said.

The question is, will the economy continue to improve, giving Obama a boost, enough to bring back some of the excitement that swept him into office four years ago?

"People are not as excited, the youth, you don't see the excitement among the election that existed four years ago," Alkhatib said.

Alkhatib said while many of his students are not concerned about Obama's and Romney's faith backgrounds nor Obama's birthplace, some have said their parents and grandparents are.

Romney needs 68 more delegates to win the nomination. The next primary is on Tuesday in Texas, where 152 delegates are up for grabs.
