Step up and do what?
He can't really come out and state that he is for X or against Y since there is likely video or audio of him taking the opposite position in the recent past.
So more of "Obama Bad" is coming out...
That contradictory stuff only bothers you Obamaphiles when it is Mitt or any other opponent of the one who does it.
You all completely overlook, disregard, excuse and make mindless apologies for ALL of the innumerable times President Obama flips and flops.
The Panderer in Chief is maybe one of the worst offenders.
So, let's jut be blunt. Mitt absolutely CAN and should step the **** UP and put voice to what he WOULD do and what he does stand for. And if the comically dishonest liberal Dumbocraps dare to try to paint Mitt as dishonest or flip-flopping, that's fine by me. The same can easily be done to the various positions taken by The ONE and ALL of the examples of his doing so should be fully aired and exploited.
And, by the way. The incumbent IS bad. He is a disaster. He cannot run on HIS record which is why he isn't even pretending to TRY to do so. He is busy running FROM his record (which is the only smart thing he can do). But he needs to be CALLED on it. Endlessly.
