The Fix’s graphic says it all:
A quick run of the numbers says that Romney has won about 55% of all the delegates this far, and he’s a bit over 1/3 of the way to winning the nomination.
He needs about half of the remaining votes to win, as versus 2/3 for the Santorum.
The only reason that we are still seeing a race is because the press hates Romney worse than it hated Al Gore in 2012.
Really, absent a live boy or dead girl in his bed, Romney is the nominee, particularly when you consider the number of unelected delegates, congressmen and whatnot, who won’t vote for Santorum or Gingrich if you put a gun to head.
