Trump's victory honestly is - as horrible as it sounds to say this - is a glorious godsend to the Democrats. The timing, the man, and the coalition is great for the Democrats.
Here's how.
Trump is taking over at the peak of the economic cycle. That means with 5% unemployment, rising wage growth, and no economic recession since 2009, what's that mean? It means that there is no crisis to manipulate, no economic "come back" story to stage for the GOP. And it also means there will be a recession at some point during Trump/Pence's term.
So, the GOP gets saddled with the economy at the very moment it's at the climax. It means it's downhill from now. Remember, the last successful GOP presidency took power at the moment the economy was in the doldrums (Morning in America)? In 1992, Clinton took power JUST as the economy was taking off but unemployment was still at 7.2% when Bush Senior left office. Clinton's timing was amazing as the 1989-1990 recession was right before he took power. W took office again with very low unemployment and we all know how that turned out.
Second, Trump himself is working with a very limited older white working class coalition. He lost minorities by huge margins and given his promises to his base, will be unable to bring Latinos to the 40s, and raise his AA appeal significantly. Of course, he could still, but given the intensity and the polarization of the GOP base and the country, it's very unlikely. And of course, he lost large swaths of younger white voters.
There are a number of economic and budget crises facing the GOP now (not least unwinding ObamaCare) that the GOP must slog through and lose serious political capital on.
Imagine if Hillary had won. She would be facing a GOP House, an economic recession between now and 2020, and historically low approval ratings. Instead, that's all now on Trump.
So, why demonize Trump? It's much smarter to construct an alternative to the Trump GOP and win for good the loyalty of a swath of voters who can put you in power and allow you to enact your agenda.
The GOP's best bet is to impeach Trump in <2 years, after he's done something outrageously bad and offensive even for him. Then they can use him as a scapegoat for the next decade, and hold up their willingness to impeach him as some sort of proof of how "good" they are.
