But this is not a normal convention. Donald Trump is dismantling the Republican Party and replacing it with a personality cult. The G.O.P. is not dividing; it’s ceasing to exist as a coherent institution.

The only speaker here who clearly understands this is Ted Cruz. He understands that the Trump phenomenon is probably not going to end the way a normal candidacy ends. It’s going to end catastrophically, in November or beyond, with the party infrastructure in tatters, with every mealy mouthed pseudo-Trump accommodationist permanently stained.

Some rich children are careless that way; they break things and other people have to clean up the mess.

I’m not a Cruz fan, but his naked ambition does fuel amazing courage. As the Republican Party is slouching off on a suicide march, at least Cruz is standing athwart history yelling “Stop!” When the Trump train implodes, the docile followers who are now booing and denouncing Ted Cruz will claim they were on his side all along.
