Subject: Re: How indeed...
I think it is some combination of secret prejudices the right has had buried for a long time, and the partisan thought of "at least he's not a Democrat". I'm sure many think that the worst Republican is better than the best Democrat. A very distorted view, in my opinion, but I have no doubt many hold it.

The secret prejudices are self-explanatory. They've been given permission to let it all hang out now, by a POTUS that reflects that attitudes.
