The GOP came ready to rumble tonight.

Two former governors and presidential candidates themselves—Mitt Romney of Massachusetts and Mike Huckabee of Arkansas—came out swinging against Barack Obama, Joe Biden and the Democratic Party. More on those speeches later, but they each had memorable sound bites.

Rudy Guiliani is next. Expect him to set the stage for Sarah Palin by laying the framework for her argument about experience; expect her to demonstrate in her speech that she, too, is ready to rumble.
