Whatever. Trump is being Trump, people know better by now. The only people upset are the ones who have never voted against a Democrat in their life.
Get a grip, people!
Just making observations. You are right that there are lots of voters locked in on both sides and statements like this will not affect them. However clumsy statements like this will reduce Trump’s ability to secure independent votes in key battleground states.
Trump has a great opportunity here. As you say Trump is Trump. He doesn’t listen to advisors or anybody so the election is all in his hands ... and mouth.
