KNOXVILLE, Tenn. (WVLT) --- The race for the GOP nomination for President has landed in Tennessee.

So have the campaign ads.

Millions of dollars are expected to be spent statewide, much of that will be spent by SuperPACs.

Groups that work to push a candidate's campaign forward, without working for the candidate.

After a 2010 Supreme Court Decision with the group Citizen's United those SuperPACs can have unlimited money to spend.

But what are they spending it on?

"The level of attacks in the SuperPAC ads across the board have been high. Much higher than advocacy and there is a high level of uncorrected deception." We talked to Dr Kathleen Jamieson, who's bi-partisan website Flackcheck.org looks at each campaign ad.

She's worried that 2012, the first year after the Citizen's United ruling, could be the dirtiest year yet.

And it's because of that deception.

Political ads, according the the Supreme Court, are free speech.

And they can stretch the truth or blatantly lie.

"These candidates are all being disadvantaged by this deception," Jamieson told us in a phone interview, "and the Electorate is being hurt to, because it might cast a misinformed vote."

We took a look at three ads that have been running in the majority of states so far, you can find them by clicking the video link with this story.

You can also find more on Flackcheck's website, which we've included a link to in this story.

Flackcheck is hoping voters will check the ads out before hitting the polls.

And if you think these ads have crossed the line, get ready for the general election, when both parties campaign against each other.
