I think most Trump supporters would agree he has had a bad week, whether polls (excluding Sruvey Monkey/ Morning Consult), the Lewandowski thing, the Heidi Cruz backlash, and the non-stop attacks from the Ryan-Walker cabal.
And in this terrible, very bad week Trump was the only candidate to gain delegates, 12 of ‘em from MO, even though there is no primary going on.
The Republican Party as a whole has had a bad week.
Mostly agree with what you said about a rough week...but, there are actually a number of polls which came out that look good for Trump...go to realpolitics.com and take a look.
I did not know about Missouri...that is good news...will offset a loss in Wisconsin(which will split their delegates)
