Well, when he can’t get the nomination in the RP, don’t count it out. That’s the next thud to hit the floor IMO.
All of the other GOP candidates are going broke and they don't have money for Super Duper Tuesday ad buys. And they don't have the grassroots that Paul has.
So I wouldn't count Paul out yet. Even Tim Russert said Paul will be in up through the convention. And he'll have his seat at the table and his moment in the sun even if he's not nominated. And that's what's really important.
