But is Trump entirely to blame? Absolutely not. The Donald cannot take responsibility for the profound divisions in his party or the decline of good governance. These predate him by many, many years.

Trump has tried to blame the Democrats. That's outrageous. It's true that not one of them backed the Republican alternative to Obamacare, which some call Trumpcare - but the GOP has a majority in the House and should, theoretically, have been able to get it passed without outside help. No, the problem didn't lie with the Left but with the Right. All the years that the Republicans were united by opposition to Obamacare disguised the fact that they couldn't agree on what to replace it with.
