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.
Then it is too early for Rand Paul to be sucking up to Mitch McConnell. Why not endorse the conservative running for that seat? That might actually give the guy some exposure. No Principles Rand Paul!!!!
