When Trump attacked Khizr Khan before the 2016 presidential election, anyone decent and moral should have known all they needed to know about Trump and should have voted for anyone other than Trump.
I feel about the same way — there just isn’t any good excuse for not knowing what a godawful anti-American liar and scam-artist Donald Trump is. He made clear his contempt for the First Amendment freedoms of speech, the press, and religion, long before the election; his shabby business conduct was well-documented; his serial lies were the subject of public wonder.
The people who voted for Trump knew who he was — and have no excuse.
