During the 2015/16 campaign, Donald Trump performed what I would consider a public service by laying bare the differences in ideology among the various factions of the Republican Party. The GOP cannot actually govern, however, unless those differences can be resolved, or at least papered over. Some of that task can be delegated to Ryan and McConnell, but some of it is up to Trump.
He can’t do it. His personality, to say the least, is abrasive, not soothing or placid. He doesn’t have positive relationships with enough members of Congress to sway votes. His poll ratings don’t indicate that he can rely on the bully pulpit to intimidate wayward GOP members. Finally, he knows practically nothing about policy, so he can’t help with the detail work. All he can do is call meetings at the White House and fruitlessly demand victories for himself.
It certainly doesn’t bode well for the future. He needs a war or a terrorist attack to turn things around, and soon.
