With that said, I could easily flip your point around and comment that Trump is getting pilloried for many of the same things that Obama did without incident. I suspect that much of what you're identifying is partisanship at work, and partisan myopia is nothing new.
Maybe, it depends. For instance, the golf issue - I never had a problem with Obama's vacations but I do with Trump's, but only because Trump so far seems set to spend what Obama did over 2 terms, in just a single year, even after Trump spent years complaining about Obama's golfing and even said he (Trump) may not play any golf as president (lol). Presidents need time to unwind, but within reason. Trump is casually treating the country's tax base as his own personal piggy bank in this regard.
Anyway, my point is, considering Trump was extremely well-covered, people who voted for him bear some responsibility in his success
(or lack thereof). This is especially applicable, imo, to the party of personal responsibility. All Trump's conflicts of interests, his extensive history of lying, cheating and bad business practices, his intense hypocrisy, his lack of desire to actually learn anything about govt, his brash nature, the near-complete lack of ethics/morals - this was all on full display well before the election. People who willfully ignored this cannot, imo, be completely let off the hook.
But also keeping in mind that when I say "let off the hook," I'm only saying, they have absolutely no grounds to say what happens isn't partly their fault. The same goes for any person who votes for a candidate who is so transparent in their shortcomings, Democrat or Republican.
