Trump needs to ignore stuff like this. Laugh it off. Say, yes, I need to loose weight, just like Clinton and many Americans.
He took the bait on this one. This is how they will bait him in the debates.
I wish I could take credit for telling Trump to do this in a post late last night, but the response to me seemed so obvious that he didn't need anyone to tell him what to say (Post #4 on this thread):
I absolutely expect Donald Trump to issue a Twitter message tonight, pointing out that he's never gotten his @ss kicked by an exercise machine. And that will be the last we hear from Harry Reid, I'm sure.
LOL.
