The thing is, he seems to have a habit of saying and doing what people who help him move up the political ladder tell him to say and do. I wouldn't be surprised if he thought being a good lapdog is what class is all about.
Having a loyal little lapdog tell Trump he doesn't have "class"? What I'd think of as having no class is Rubio backstabbing the people who actually vote for him.
Perhaps it's like Survivor. Trump might want Rubio around for awhile and get rid of more capable competition first. This is a whole new level, the dwarfs having to worry about what Trump will say about them. Love it.
Did Rubio ever say that Hillary Clinton has no class? (which is eminently true and proven)
No?
Why not?
