Hillary Clinton When They Go Low, I Go JLO

Jennifer Lopez has done her research, and the verdict is in ... JLO's with her.

Lopez brought Hillary Clinton on stage in Miami Saturday night, with a rousing endorsement.  Hillary took a shot at Trump at end of the show, and JLo doubled down by singing "Respect."

BTW ... JLo's ex, Marc Anthony, was back again with the mother of his kids ... right there on stage.
