Am I wrong?

According to my math, Santorum needs to win like 70% of the remaining delegates to reach the magic number of 1144 and win the nomination in June.  With some of the biggest States still to vote (CA, NY, IL, etc)... this is a tall order to fill.

The up-side is that, thus far, only Romney and Santorum have enough delegates to get their names on the ballots at the RNC.  It is pretty unlikely that Gingrich is going to reach the 5-State requirement, even with so much of the South still voting... and Ron Paul won't win a State period.  That means, given a perfect scenario, Romney will have to pick Santorum as his running mate for the run to November.  It is as close to a "unified" Republican front as we are likely to see... and it will have to be enough to win back the White House.
