Good point. If Obama & Hillary denounce Brexit, that does her no good in November. They don’t like this one bit.
Maybe they’ll criticize Trump for being in Scotland & spreading his bad vibes throughout the British Isles. Undue influence, yeah, that’ll work.

If anything, our trade policies should be based on who is most like us and who is least like us. Those most like us should get free trade. Those nations least like our traditions like the Chinese should not be granted free trade privileges. Yes, trade with the USA is a privilege one has to earn.
Nations like Mexico in my economic trade scheme would fall somewhere in the middle as a nation that kind of is like the USA in institutions but fails at achieving their running to our standards.
