The Republican Party (and the rest of the nation) MUST move on from Trump, and the way that that will happen is that he and the Republican Party are not just defeated but repudiated and all but destroyed.
In fact, the Republican Party is going to be historically renounced and repudiated in November. I think the Republican Party knows this. Then, after November, the Republican Party can come to its senses, dump Trump and the MAGAts, dump the gunnuts, dump the white supremacists and the biblethumpers, dump the old Tea Partiers, and get back to governing.
