There is no doubt in my mind this country is divided, and people who want to hang that on Donald Trump are, well, FOS. This has been going on since Perot got rid of Bush the Elder in 1992. The Rats have been pushing the envelope ever since they got the White Hut back after 12 years under Reagan, and then sort of Bush 41. (I will always remember the era not as "Reagan-bush, then Clinton," but rather "Reagan, then Bush-Clinton.")
It was already in full swing when they tried to steal the Election in 2000. The lefties spent the Clinton years reinforcing their grip and kicking out the Old Guard. The political spectators have been decrying the so-called moderates being driven out since 1994.
And now, we are to believe a fellow who never really dabbled in Politics until 2014 is responsible for 30 years of polarization?
