Just to flirt with the idea of Ron Paul still winning, I share with you the happenings at the Nevada State GOP convention, where the national delegates were to be voted...

In short summary, the Paul supporters outnumbered everybody and used this to vote a change in the delegate nomination process which set them up to win nearly ALL of the states 31 delegates for the national convention. Of course this confused the mainstream media who already claimed McCain had won the majority of Nevada's delegates (which Romney suppossedly had but in reality didn't own either.)
Many states use the state delegate process and McCain hasn't won the nomination yet. I'm not saying Paul will win, but I will say his supporters will continue to fight since they know the actual rules and how to get their guys support.
