Automation, globalization, and anti-unionization have been pushing down wages for 30+ years. Government policies by both parties seem to do nothing but speed up the process, particularly in globalization. The only thing the Dems had to offer was social safety net, but most people would rather have better paying jobs. The Republicans only offered rhetoric and an extra helping of anti-unionization.

Also, I don't think a vote for Trump is for the GOP or their policies. The GOP was the platform Trump used to get elected (as he slashed and burned their policies). I think the vote was anti-establishment (anti-GOP and anti-Dem). It could be a sign of just how economically desperate many people in the red areas are.

Also, it's very difficult / rare for a party to get a third term in recent history.

I'm not from one of the "Brexit States", but my family is spread across much of the rural Midwest and that sentence expresses their feelings quite succinctly. One family member, during a conversation about tech, volunteered that he thinks self-driving trucks will destroy much of what's left of the patchwork of small towns remaining near where he lives. No more relatively predictable income from truckers at diners and gas stations when the battery powered robots never have to stop for food or gas.

- I clamor for women's rights but when a certain religion is guilty of trampling over women's rights, I go quiet

- I clamor for equality before law but when a certain religion asks for different laws for different religions, I go quiet

People don't take too lightly to their sense of fairness being trampled over, and this feeling of unfairness seems to be a cause for growing discontent.
