Three days after House Majority Leader Eric Cantor became national political news fodder by losing a primary election to tea party challenger Dave Brat, embattled GOP Sen. Thad Cochran has seemingly no idea what happened. To repeat: A sitting U.S. Senator has no idea that the second-most important member of his own party in the U.S. House of Representatives was just unseated in a major primary defeat. During an interview with Fox News on Friday, Cochran was asked whether he believes Cantor’s defeat means anything for his own Mississippi GOP primary runoff election against Tea Party challenger Chris McDaniel. The exchange that followed is… surprising.
