The fracture is now a chasm. The food fight between Trump and anti Trump forces isn't even entertaining anymore. And what's worse, all this madness has paved the way for Queen Hillary I.
You're right that it's madness. But it's madness started and fueled by Donald Trump.
Trump jumped into the presidential race on a lark, a grasping for attention. Even he didn't expect to get anywhere. That's proven by the fact he never spent a dime, never hired any serious campaign staff, and had no policy positions to speak of but his boob bait wall.
Then he realized there was a group who was buying his bullshit, and he doubled down on his nativist streak: ban Muslim immigration, impose 45% tariffs on our largest trading partners, bring back waterboarding. He capitalized on all the free media the nets and cable channels gave him and continued with the game.
Did anybody think he was really serious? I mean, look at the man. He's an MLM scam artist, making money by sticking his name on buildings built and owned by other people. THIS is a presidential figure, this crude, nasty, insulting vulgarian, an admitted adulterer and blatant misogynist? He's tapped into anger, but, instead of diffusing it, he's harnessed it to appeal to the basest emotions of a 37% segment of the GOP.
Now that he's almost caught the car, the deer in the headlights look is about to take over. He fumbled the delegate situation in Louisiana because he has no one to manage that process, his Iowa operation has shut down (this is unbelievable!), he's made a series of foreign policy gaffes (after naming a team of minor league characters to advise him and he's yet to consult them), and he drove up his unfavorables with women in a fit of personal pique over a pic that few people hadn't already seen.
Couple that with his poll numbers against either Democrat in the race, and Trump is suddenly in trouble. It's easy to see him losing Wisconsin, underperforming in California, not having the 1237 by July, and losing at the Convention.
The GOP is coming to its senses, finally.
