Bill and Hillary Clinton are getting involved in the effort to oust Senate Minority Leader Mitch McConnell. The former president recently campaigned for the Democrat, Alison Lundergan Grimes, and Hillary is scheduled to do the same this weekend.

Sen. Rand Paul (R-Ky.), however, believes the former First Lady will have no effect on the outcome and that McConnell will be re-elected. 

He argued that the Clintons have a false impression that they were popular in Kentucky when Bill Clinton won the presidency. 

"The Clintons think they were popular in Kentucky like 20 years ago. They only won when we had [Ross] Perot on the ballot. There never has been a majority of Kentuckians who really are that fond of the Clintons and really a lot of water’s passed under that bridge since then. I don’t think they’ll have any influence on the race and I don’t think Mrs. Grimes can win," said Paul, adding that the election is a referendum on President Obama. 

"Frankly, everything he’s touched this year has turned to stone," said Paul, pointing out that the state has less jobs than in 2008.

Paul believes that if Republicans win the Senate, they will be passing legislation on immigration, tax and regulatory reform. He said the onus would then be on President Obama to work with the GOP. 

"We will find out, is the president going to be a leader or is the president going to be an obstructionist?" he asked.

Watch the discussion above.
