Just because David Duke ran as a Democrat, it doesn’t mean the Democrats accepted him. They didn’t. He had to do that, because he was running against an incumbent Republican. You can’t use the local political situation of party politics to change the fact that he is a Republican in his base of support. No doubt, he is running as a Republican this time, if he runs, and if there is no ironclad Republican already sitting in the seat. Nice try though.
People have been giving Trump a pass on all of the racist, sexist, degrading toward others comments he has made in the past 25 years, because he wasn’t trying to represent the public. The fact people can find so many examples of his horrific thinking and expression going back all of those years up until today shows he has never improved and he has consistently been a terrible person. Terrible people with money often get to be celebrities. They shouldn’t get to be leaders of great countries.
