I actually think this may be quite a problem for President Trump down the line. These are friendly, community minded people who - generally speaking - overlooked (rather than covertly support, as everyone seems to project) Trump's more outlandish/discriminatory rhetoric. If he comes up short on the community reinvestment and gets mired in a bunch of unseemly scandals, the support of these people will drop off.
That said, what people think is true is - of course - whatever they can be convinced is true. Immigration really isn't/hasn't been a problem, so if the president can build an unnecessary wall and convince people that immigration isn't a problem anymore because of it then maybe we're boned.
Its was very symmetric.
an election is a choice between 2 alternates though
didn't like X (maybe 'thought X would do bad things' is a better way to translate that), is a valid reason to vote for Y, and doesn't translate very well to "just to fuck with everyone"
---------
if you dislike Trump, the Democratic Party's failure to give the American people a better alternative to Trump than Clinton, deserves some portion of the blame
(and while we're on it, the medias failure to hold the democratic party accountable to produce better options than Trump deserve a good deal of the blame as well)
-----------
These things work in balance, Trump gets away with a lot of the stuff he gets away with, because people don't trust the alternatives,
people don't trust the alternatives, because those alternatives have proven themselves unworthy of trust
