The math doesn’t lie.
While the GOP is busy eating its own and conservatives can’t seem to agree on a consensus candidate sufficiently extreme enough - Rick Santorum or Newt Gingrich, the fact is that Mitt Romney will win the nomination.
There are 2,286 delegates at stake and it takes 1,144 to win the nomination.
Thus far, Romney has won 455 and Santorum has won 199 to Gingrich’s 117. Ron Paul has won 64.
That means that 1,557 delegates remain to be divided up. Even if Rick Santorum wins 60% of the remaining delegates, he’d fall short by 11 (11.2) to capture the nomination. He’d only manage 1,133.2 if he wins 60%. He hasn’t done that well in the popular vote overall, and he would have to do so much better than he has to date that it’s inconceivable.
The math is even worse for Gingrich. He’d have to win more than 66% of the delegates remaining.
