For the last week Trump has been attacking Rubio left and right, which I’m guessing is exactly where Rubio wants to be since it means he’s over the target. Today is the Values Voter Summit, and while Rubio spoke articulately with class this morning, Trump took to the stage and aimed his mindless ramblings towards none other than the Florida Senator.

Conservatives booed Donald Trump for calling Republican presidential rival Marco Rubio a “clown” at the Values Voter conference of activists on Friday.

“You have this clown, Marco Rubio,” Trump said, as the crowd erupted in boos. “I’ve been so nice to him.”

Trump has turned his rhetorical fire against Rubio in recent days as the Florida senator has risen in the polls. After the booing, Trump tried to attack Rubio for his support of a comprehensive immigration package two years ago, saying there was “nobody weaker” on immigration. The attacks received a damp reception. Trump eventually retreated back to safer ground, attacking Democrats and promoting himself.

Twitter followers could sense the undoing of Trump’s vitriolic narrative as it began slowly dying in the room. His ramblings may be cute with faceless keyboard warriors who can’t wait to retweet his latest tantrum, but they did very little for him on that stage.

Trump calls Rubio a "clown," the crowd boos loudly.

Trump almost got booed off stage and is now just stammering on about contracts or something.
