The non-Romney front runner’s path to nomination:

Delegates won so far by Santorum = 212
More delegates needed to win nomination = 932
Delegates remaining in future primaries = 1499

Santorum needs to win 932/1499 = 62.2% of all remaining delegates.

Most coming primaries are proportional. Winner take all are:
UT, NJ, CA, DE, DC none of which are Santorum’s strongholds.

CA is not winner take all exactly. It is WTA by CD. There’s at least 15 CD’s Santorum would be favored in.

And that's the good news! 4th and long field goal with 18 seconds left to tie the game and send it into overtime (the convention).

Newt, on the other hand, has 107 delegates. With 1144 needed to secure the nomination, he only needs to win (1144-107)/1459 or 71.1% of all remaining delegates.

And Romney? He has 454. So, using the same math (1144-454)/1459 = 47.3% of all remaining delegates.

Ron Paul? He has 47. So he needs (1144-47)/1459 = 75.2% of all remaining delegates.
