Marco Rubio took a dig at the size of Donald Trump's hands.
Trump took a jab at Rubio's size saying, "Who is the lightweight Rubio? Total lightweight. And a little mouth on him."

People in eleven states are casting their votes for the Super Tuesday primaries. Candidates have put their campaigns in overdrive, and the tone of some campaigns have taken a left turn.
Early in the Republican presidential race candidates seemed to shy away from Donald Trump's jabs, but things have changed. Marco Rubio has taken his turn at slinging mud with Trump.
"He sweats more than any young person I've ever seen in my life." Trump said referring to Marco Rubio.
Rubio fired back,
"He doesn't sweat because his pours are clogged up from the spray tan that he uses." Said the Florida senator.
That was not the only dig Rubio took at Trump.
"Donald is not gonna make America great. He's gonna make America orange," he added.
USC political science teaching assistant, Stephanie Davis says there is a reason for these attacks.
"The reason that candidates attack their opponents like this is often perceived as weaken efficiency in their campaign. So what they're doing isn't working, so they try and switch."
This is not the first time politicians have engaged in this strategy, but Trump has brought a different approach.
"So they happen to work with somebody whose not playing the game that they know. So perhaps what Rubio is doing is trying to play the game that Trump is playing." Davis said.
Rubio and other candidates are looking for a strong finish in the Super Tuesday primaries to close the gap on Trump. 595 delegates are at stake in the Super Tuesday states. There are 2,340 delegates at the GOP convention, and 1,237 are needed for nomination.
