Has Trump attacked a Democrat lately, or is he's too busy attacking the Republican field?
I wished you a good night and was about to head off for sleep...but "...they keep pulling me back in..." :)
As I see things, it's primary season and Trump is calling out the RINOs, They're just as far to the left as are the DemonKKKrats. I think this is just Trump tuning up his attack machine on the low-hanging fruit of those self-identified as Republicans. Once the field of the R-branded candidates solidifies, and presuming he continues to show strength, he'll then unleash his considerable wrath and torrent of words on the Klan's party.
I hope that answered your question because I'm running out of steam and am about to doze off.
I have heard him go after Hillary more than i have heard anybody else do it. He has gone after Graham a bit too which is almost as good.
