In an interview with Yahoo News, Senate Republican Leader Mitch McConnell admits he could face a tough primary challenge from the Tea Party in his home state of Kentucky.Since its inception the Tea Party has been critical of McConnell's leadership despite hisefforts to make peace with the movement. The strife has increased in recent weeks, with over a dozen Tea Party groups in Kentucky warning that a primary challenger is forthcoming.McConnell says he doesn't have a sense of entitlement to the senate seat, and expects a vigorous campaign.From Yahoo News: McConnell acknowledged he may face a tough primary challenge in 2014, in part because he has been at odds with tea party members in his state and because those in Senate leadership roles in both parties are juicy targets for defeat. Could that mean a Sen. Ashley Judd, who is considering running for the Democratic nomination in Kentucky? "Who I actually end up running against either in the primary or the general will be determined in 2014 and we'll take a look at it then," McConnell said.McConnell says his relationship with Sen. Rand Paul, R-Ky., has been helpful and he's grateful for Paul's endorsement for re-election.The wide-ranging discussion included McConnell's thoughts on gun control, abortion and President Obama's upcoming State of the Union address. He also explained how he and Vice President Joe Biden were able to strike a deal to avoid tax increases during the fiscal cliff negotiations.
