Shades of Arlen Specter and Rick Santorum. Didn’t go to well for Rick after his endorsement. In my opinion Old Mitch has been there to long and his spine has turned to jelly.
Too early to compare it to Specter, Santorum and Toomey. As bad as McConnell is, he’s not as bad as Specter - and from what I can tell, there isn’t a “Pat Toomey” already in the race in Kentucky now.
