“All of my employees are having a tremendous problem with Obamacare,” Trump ad-libbed.

Well, Obamacare was the issue of the day. Except the workers in question had employer-covered health plans. Whoops. Somebody must have violated the 30-second rule on the flight in.

It’s still possible to get a drooping candidate exercised, as long as you stick to the personal. Witness Joe Biden’s recent comment that he’d like to take Trump “behind the gym if I were in high school.”

“Did you see where Biden wants to take me to the back of the barn?” Trump demanded, starting off with his signature inability to get any fact right, including the proposed location of the fight. “Me! He wants it, I’d love that! I’d love that! Mr. Tough Guy. You know, he’s Mr. Tough Guy. You know when he’s Mr. Tough Guy? When he’s standing behind a microphone by himself!”

O.K., not the man you want negotiating an arms reduction treaty.

Do you think Clinton thinks she’s a shoo-in? Publicly, she’s not talking that way. And there’s no reason to get overconfident. Florida seems to be tightening. There’s no telling what might happen, given the fact that we live in a country where Donald Trump is the Republican nominee for president.

But you’d definitely rather be the campaign with Barack and Michelle Obama rallying the troops than the one that has to rely on Rudy Giuliani, Chris Christie and Newt Gingrich. The men who give a whole new frightening image of the Three Amigos.

Of the trio, Newt is clearly the winner. Having come into the campaign as political wreckage, he’s the only one who doesn’t cause people to shake their heads and say, “My God, what happened to him?”
