It's a toss-up whether Republicans are more afraid of a third-party run by Trump or of Trump himself

What a pathetic bunch of cowards:

Trump has upended the Republican Party since he launched his campaign. He boxed in all of his rivals with his incendiary comments about undocumented Mexican immigrants as rapists and drug dealers when he kicked off his run, yanking the rest of the party to the right ...

He reached new levels with his proposal this week to ban Muslims in the wake of the San Bernardino shootings, setting off an international outcry that again has the rest of the Republican Party scrambling for cover.

Oh, the poor, poor Republicans! Forced to cower in silence because the leading contender for their party’s presidential nomination forgot spew his bigotry and hatred in the carefully coded language the GOP has perfected and been peddling for years. The humanity!

And now with Trump once again floating the idea of a third-party run if he doesn’t get the nomination—or if he doesn’t get enough respect from the GOP establishment—the party is in a panic. A cowering panic anyway, which is evidenced by RNC Chairman Reince Priebus, lacking the guts to do it himself, sending out a lackey to issue a sobbing statement, reminding Trump that he signed a pledge to support whoever the nominee was. Now that’s leadership. In Bizarro World.
