President Trump’s main worry when it comes to the firebrand, young liberal who just tossed his hat in the 2020 ring?

He gesticulates too much.

“Well I think he’s got a lot of hand movement, I’ve never seen so much hand movement,” Trump told reporters in the White House on Thursday when asked about Beto O’Rourke’s candidacy. “I said, ‘Is he crazy or is that just the way he acts?’ I’ve never seen hand movement. I watched him a little while this morning doing, I assume it was some kind of a news conference, and I’ve actually never seen anything like it. Study it. I’m sure you’ll agree.”

Trump also refused to say whether he thought O’Rourke or former Vice President Joe Biden was a more concerning candidate.

“Whoever it is, I’ll take him or her on,” he said.

Trump is reportedly most intimidated by a possible Biden presidential bid, even though the former vice president hasn’t yet announced his decision. Trump’s allies are reportedly concerned about O’Rourke, who fought an unsuccessful Senate race against Sen. Ted Cruz (R-TX) but shocked the masses with his record campaign fundraising.
