I'll say this again for those who didn't catch it in the other thread I posted in.

Are you all listening?,....... Newt Gingrich will not be the Republican nominee before the convention. Talking about it is a complete waste of time. (Some of you seem to enjoy that kind of thing, so congratulations?)

Both him and Santorum failed to gain ballot access in states equaling 564 delegates. That means there is no mathmatical scenario in which either of them garner the needed 1,144 delegates needed to secure the nomination. The only possible scenario in which either of them could win is a brokered convention in which there is no clear nominee after the first round of voting at the convention and all obligated delegates are released to vote as they please.

Only Romney and Paul are on all 50 state primary and caucus ballots.
