Matt Bevin seemed like the ideal candidate to challenge Mitch McConnell. The handsome and personable businessman, a father of nine, impressed national conservative groups looking for a chance to knock off the Senate Republican leader. These groups, from the Senate Conservatives Fund to FreedomWorks, the Tea Party Patriots and the Madison Project, invested more than $1 million in the Kentucky GOP primary. Bevin himself spent more than $3 million, including $1 million of his own fortune. And, yet, polls indicate he’s going to get creamed Tuesday.
