It seems to me that the existing Trump opposition will stay the same: the vast majority of the Democrats, immigrant groups, and the majority of millenials will not become fans of Trump’s vulgarisms or idiocies. The only hope in the Trump opposition in terms of growth or potentially affecting all other groups is the Republicans. While the Party has been ineffectual in Trump opposition, it is also the group that stands the most to lose in the case of a Trump backlash. While these are the people who sucked up to G,W. until it was no longer expedient to do so, judging their morality or guts is a sure loser. But if enough of them find their way it is just possible the rogue President will no longer be so.
“The Republican Senator broke with the reassuring message that US officials visiting Germany have sought to convey on their debut trip to Europe, telling a Munich security conference the resignation of the new president’s security adviser, Michael Flynn, over his contacts with Russia reflected deep problems in Washington.
“I think that the Flynn issue obviously is something that shows that in many respects this administration is in disarray and they’ve got a lot of work to do,” said McCain, a known Trump critic, even as he praised Trump’s defence secretary. “The president, I think, makes statements [and] on other occasions contradicts himself. So we’ve learned to watch what the president does as opposed to what he says,” he said.
Without mentioning the president’s name, McCain lamented a shift in the US and Europe away from the “universal values” that forged the Nato alliance seven decades ago. McCain also said the alliance’s founders would be “alarmed by the growing inability, and even unwillingness, to separate truth from lies.”
The chairman of the Armed Services Committee, said “more and more of our fellow citizens seem to be flirting with authoritarianism and romanticising it as our moral equivalent”. The senator also regretted the “hardening resentment we see toward immigrants, and refugees, and minority groups, especially Muslims”.
European governments have been unsettled by the signals sent by Trump on a range of foreign policy issues ranging from Nato and Russia to Iran, Israel and European integration.” https://www.theguardian.com/us-news/2017/feb/18/john-mccain-savages-donald-trump-administration-inability-separate-truth-from-lies
