They don’t represent all the Republicans as there are those who have endorsed Trump. Not a single elected Democrat (other than Jim Webb) has endorsed Trump nor will they. Why are we mad at the establishment? It’s because they refuse to fight for conservative values. It makes no sense to teach the Republican establishment a lesson by picking a Democrat VP. That would be the equivalent of Bernie Sanders teaching the Democrats a lesson by picking a Republican, and you know no Democrat would ever do that.
We need to start over, of course with Republicans that are willing to get on board with Trump's vision welcome with open arms. Flynn's not a problem....the only political statements he's made are against Obama's handling of terrorism. Besides that, his focus will be shoring up the military and de-escalating the violence in the US.
