Or a large percentage of the populace is afraid. Nobody wants to draw the attention of the far right, both the parts in and out of office. Everyone in the US knows someone who is illegal, a green car holder, a student/work visa holder or who otherwise may be vulnerable. Piss off the wrong people and the powers that be may cast their eye on you and your friends. Even if deportation is remote for any of my immediate friends, I dont want my name on one of those lists, such as the lists of enemy attornies/firms that have recently had to make "donations" and pledges.
This is why ballots are secret. At least for now.
