can Republicans reconcile themselves to Donald Trump and Ted Cruz? Or will the GOP break into pieces?

...Perhaps the GOP’s chaos is just normal pre-primary tension, when an active contest naturally creates an air of conflict, and candidates have an incentive to warn against their rivals in urgent terms. But for many Republicans—the ones not living in fantasyland—the current battle for the party, between the nihilistic forces of Trump and Cruz on the one hand and the uninspiring conventional politicians on the other, feels like something deeper. It feels like a duel from which only one participant will walk away. It feels like the party is on the brink of breaking apart.
