Common Sense Issues, the right-wing group that has been running independent ads and a whole separate campaign operation on behalf of Mike Huckabee, has a new ad set to run tomorrow in Iowa, mocking Mitt Romney's changes of heart on abortion:

The ad is cleverly constructed, doing a send-up of Romney's "Two former governors..." format from his own ads, and even adding in a diabolical laugh — as if to say Mitt is giggling at the thought of all those fools who fall for his act.
