Rove stated that more candidates makes for a better outcome, they need to be scrutinized to get disciplined candidates that can win...more Rand Pauls and fewer ChristineO’Donnells.
He supported Rand Paul and Marco Rubio.
If you are quoting Rove on that point - Rand earlier stated that Rove back his opponent, (I think) in the primary. Not much of a leap for Karl to then say he backed Rand once he won the primary - real commitment there Karl!
