Catherine Hepburn has no principles. She’s wants her fellow worthless RINO to be successful but doesn’t want to be held accountable for it.
Collins has the same principles as the people of Wisconsin.
The WI voters like democrats (see election of 2012) but they are opposed to recalls (see recall elections of 2011).
Collins is opposed to Hagle (floor vote) but is opposed to fillibuster (cloture vote).
