I mean, Mcconel is slightly right about only backing candidates who can actually win.

Like Roy Moore... That was a poor move to endorse him. I know Trump had hoped his endorsement would've propelled him to the win, but it wasn't a good choice for office.

We all make mistakes. Trump has his methods. #1 of Trumps being, whoever he endorses will be the most popular of the republican picks. That'd just how it is, because we listen to Trump and try to help him as he has helped all of us.
