I prefer a Middle Eastern or African to a Trump supporter. It's just too dangerous to let them in to spread their ideology. ;-)

Safe to say, Trump supporters aren't traveling to europe.

This isn't true, his base of support is motivated by any number of factors and many of them are financially well off.

Plenty of his political supporters would be happier if he behaved more like the usual politicians but will put up with his shenanigans as long as they get what they want from him.

I meant that the refugee crisis fueled populism, not that it prompted this potential visa change for US citizens.
