I'm sightly surprised by how much of it he agreed with
He's right to say that my Trump wins a bullying competition hasn't be tested yet because no one has tried to give it back. He's equally correct to say that the primary reason is because no one wants to risk alienating Trumps 30%. They're happy of course for someone else to open fire, but don't want to do so themselves. That doesn't of course mean that Trump doesn't still win this kind of street scrapping politics
Jeb Bush made one of the better observations of the campaign when he said that in order to win the White House you need to risk losing the nomination, but for all that, he hasn't really done it. I quite liked the BBC analogy of Jeb being the junior at school whose head Trump keeps pushing down the toilet and flushing on him
It kind of set me thinking that the other candidates have missed a trick here in trying to defend the soul of the party and use that as a cloak from which to attack Trump. Trump has pretty well be insulting their constituencies, or at least those demographics which they'd all hoped to reach into and convert. He's possibly made the Republican party unelectable. They've resisted doing similar to him because they'd all like a share of his core support. They don't want to be seen as picking with Trump for fear that his voting bloc interpret as an attack on them through extension.
What perhaps someone should have tried is chastising him for insulting the American people and calling him out in the name of the party. This would have positioned them as the defender of the party's reputation. Instead they've tended to frame Trump's bullying bombast through the prism of the personal insults aimed at them individually, rather than Americans generally. There was possibly a gap here to exploit, albeit it risked pushing Trump outside the party with all the potential ramifications of an independent run
In fairness to Carly, she went closer than anyone else when she said "I think the women of America clearly heard what Donald Trump said" and boy, didn't he look uncomfortable as she slapped him down.
