Washington Post columnist Michael Gerson really nails this one: Trump’s failing presidency has the GOP in a free fall.

Republicans got a leader who is impatient and easily distracted — by cable news on the Russian scandal or by Arnold Schwarzenegger’s TV ratings. The content and consequences of his tweets are bad enough; worse is the disordered personality traits they reveal — vindictiveness, shallowness and lack of discipline. Trump spent a total of 18 days on his health-care bill before demanding a vote. And he made no speech to the nation to advance his ideas — as every other recent president would have done.

Republicans got an administration that is incompetent. The White House policy process has been erratic and disorganized. It has failed to provide expert analysis or assistance to Congress and did little to effectively advocate the president’s policy in ways that could have united the party.

Republicans got an administration that is morally small. Trump’s proposed budget would require massive cuts in disease research, global development and agricultural programs — just as a famine gathers a hideous strength. The proposed budget practices random acts of gratuitous cruelty.

This is a pretty bad combination: empty, easily distracted, vindictive, shallow, impatient, incompetent and morally small. This is not the profile of a governing party.

It’s the profile of a powerful nation with an unhinged sociopath in charge, and the whole world is in ever deeper trouble the longer this goes on.
