I agree that we are at a crossroads, the world is changing rapidly in so many areas and it is sad to see Republicans willing to allow this con-artist in the WH to focus and herd them down these useless divisive paths.
It's common now to read/hear that the GOP isn't the party of Reagan and/or Lincoln anymore, and it's true, but Republicans today aren't the same as those during Nixon's years. I was young and politics wasn't on my radar but I recall similar statements about Nixon at the time and later that Trumpers use today, basically "I don't care much for the man, but I like his policies." I thought when Trump was elected he wouldn't make it through his first term, I thought he would quit amid a scandal, and similar to Nixon, only because Republicans had had enough and pulled their support. I was wrong, Republicans have changed.
