The Battle of Waterloo

Bachmann, Perry, Santorum at Black Hawk County GOP Lincoln Day Dinner Sunday night.

Santorum goes first, calls Perry's view of the 10 Amendment and gay marriage "corrupt," without naming Perry.

For a guy two days into his presidential campaign, Perry has a pretty good stump speech.

Bachmann takes stage with hoopla and delivers Iowa-centric remarks.
