The Dems have picked up on this and are now telling themselves that if Romney is our nominee they can beat him using the same tactics that the GOP used on Kerry in ‘04 (point out all of the flip-flops).
I am guessing that flip-flopping is a must-have skill to get elected to any office in Taxachusetts.
Only if you're a Republican. The path of least resistence is to just be a Democrat. ;-)
