Basically, we need 1191 delegates to win the nomination. The plan that everyone seems to be talking about involves a "brokered" convention.. that is, if nobody gets nominated on their first (or in most states, second, third, and fourth) voice role calls, the delegates can vote whomever they want. That's why SOME people here have mentioned being shadow delegates and what not.
It's a decent plan, but we need to remember that we MUST win five states to be able to select Ron Paul in the role call vote.
