Okay, just going to have a say here. It seems that many believe that a liberal in the USA must be a Democrat, pretty much following the party core teachings and some even think it means approving the party history of, during the 19th century, supporting or tolerated slavery and opposing civil rights reforms after the Civil War. Some even insist that a liberal loves anything and everything Obama did.
People are people and they don't typically fit nicely into broad categories.
If a liberal voted for Hilary Clinton, it could have been an anti-Trump vote, and vise-versa. They may not have liked "their" candidate so much as they hated giving Supreme Court nominee powers to someone with a very different ideology, or some other things may have influenced them. Or, like enough liberals apparently did, they may have refrained from voting or voted third party because "Hilary sucks" as a choice.
On and on it goes. To say that someone supports the 200+ years of history of the party by voting for its candidate is silly also. It reminds me of Watchtower yelling "Pagan" at anything they want members to stay away from like birthday cake.
Alright, I stirred it up. I said my piece.
