Yes and no. This and his supposed "racism/xenophobia" will be what they attack him on, but the movement is the strongest today that it will ever be.
The anti-trump movement is going to continually discredit itself (and with it, their fellow travelers in the MSM) and when it turns out that he's not the scary Fascist dictator they're pretending he'll be, they'll lose even more support.
As pro-American and pro-capitalist policies get implemented and the fruits of those policies start to ripen, a lot of people on their side are going to shut up (and many of them will be on our side by 2018 midterms)
All this nonsense is likely the death rattle of the left and the Democrat party as we know it.
