The Democrats could easily evolve into a liberal, regional political party.
Hillary got only 50 electoral votes from states in the interior of America. The vast majority of her support came from the liberal enclaves in the northeast and Pacific coast states.
Nobody talks much about homosexual marriage or the social issues. But the Democrats are the party of the LGBT extremists, and now they are pushing transgender bathroom access as the new civil rights issue of the day.
People are intimidated about talking about things like this, due to being branded homophobic and transphobic and all the rest. But due to this, and other marginal issues such as global warming, Democrats are losing support across the country, even as they solidify their holds on extremely liberal places such as California.
...The Democrats could easily evolve into a liberal, regional political party....
That ship has sailed. It already has according to the 2016 Electoral vote map.
Which is why we must never give up the electoral college!!
