Chris Matthews suggested Joe should attack Trump, period.
Don't take the bait from Booker or anyone else. I agree.
I'd also suggest Booker better be careful, if he throws out BS at Joe, just to try to game the night he might lose support at home. It's one thing to argue policy, it's another to bring up crap.
Likewise, Joe shouldn't mention stop & frisk that Booker supported.
Joe doesn't need to punch down.
De Blasio will be a pain in the ass, this is probably his last gasp. Same for Gillibrand. I think both will be flame throwers, with nothing to gain.

DO SOMETHING!
