Feel the Mittmentum! The new Mason-Dixon poll in Florida shows Mitt Romney grabbing the lead over John McCain:

Romney 30%
McCain 26%
Giuliani 18%
Huckabee 13%
Paul 3%

It's starting to look like McCain tops out somewhere in the mid-high 20s in this key primary — which means that Fred Thompson's withdrawal was the best thing that could have happened to Romney.
