Remember that Santorum will beat Romney in Missouri next Tuesday. Newt is not even on the ballot there. I’m hoping for a brokered convention at this point, though it is unlikely as every effort will be made to make this a two man race. If nothing else, it might actually excite some interest in the nominee.
I agree about the brokered convention. The best way for that to happen is for Santorum to stay in and win some delegates in the Midwest, Gingrich win the South and Texas, and Paul to win Virginia and some of the caucus states like Maine, Colorado, and Nevada.
Romney is going to win the big winner take all states of California, NY, and NJ so the best way to keep him from getting a majority is to keep his share in the proportional states lower and let Santorum and Paul win contests that Newt can’t win, but Romney is stil vulnerable.
