NATE SILVER: You Know, This Trump Fellow May Just Pull It Off:

But the reason I’ve been especially skeptical about Trump for most of the election cycle isn’t listed above. Nor is it because I expected Trump to spontaneously combust in national polls. Instead, I was skeptical because I assumed that influential Republicans would do almost anything they could to prevent him from being nominated. . . .

Even if the GOP is mostly in disarray, my assumption was that it would muster whatever strength it had to try to stop Trump.

But so far, the party isn’t doing much to stop Trump. Instead, it’s making such an effort against Cruz.

As Limbaugh says, they hate Trump, but they fear Cruz.
