Re. the travel thing with Trump.
A problem with the media is IMO that they run in news cycles where a few stories are "selected" and then dominate. Usually, these are "easy" stories that are quick to explain and relate to & does not require sending journalists to expensive places: "Trump promised not to go on vacation, is now on his third vacation" is one such story; you got pictures of Trump playing golf, Obama playing golf and every random pundit is an expert.
These "holiday" stories WAS a feature of the Obama presidency in his first term, I can remember that and you can find them if you google... Trump has a ton of angry tweets about it where he promises not to play golf if he is president. Bush, for his part, also got flack because he happened to be more often on "holiday" than Clinton or something
I don't know if there is a media study somewhere comparing how many such stories there was to Bush, Obama and Trump (it is likely too early), but IMO it is just what we can expect. Trump made it a bit harder for himself because his "holiday" stories also contain the angle he promised not to play golf (and here he is...), where he playes golf (at his own private club, thereby earning himself money), that he (so far) has a relatively high-security budget bc of Melania and the many travels and his son rammed up a 90'000 hotel bill on a promotional tour for a Trump hotel. <--- each of these add extra spice and give a pundit something extra to talk about.
I don't know if we can agree on these conclusions:
Every president has some "he travels too much" stories
+ Trumps stories have extra glitter (Extra cost, Eric Trumps promotional tour, on private resort earning Trump org. money, promised not to play golf)
= Trump will get more stories than usual.
IMO this is actually good news for Trump since these travel stories are going to be forgotten in 3 months.
