Cory Booker dropped out of the presidential race after former NY mayor Mike Bloomberg passed him in the national polls.

"It's with a full heart that I share this news-- I'm suspending my campaign for president," Booker tweeted on Monday morning.

Booker, 50, withdrew from the race after he learned he was polling at less than 2 percent among Democratic voters. Bloomberg is polling at 6 percent after spending nearly a quarter of his fortune on television advertising. Bloomberg recently dropped $8 million on a 30-second Super Bowl commercial.

President Trump couldn't resist mocking the New Jersey senator in a tweet following Booker's announcement.

"Really Big Breaking News (Kidding)," Trump wrote. "Booker, who is in zero polling territory, just dropped out of the Democrat Presidential Primacy race. Now I can rest easy tonight. I was sooo concerned that I would someday have to go head to head with him!"

Twitter users didn't go easy on the senator or his girlfriend, actress Rosario Dawson, 40.

Many Twitter users believe Dawson is Booker's beard. They claim Booker is on the down low and Rosario agreed to help improve his public image as a heterosexual.

"Now they can stop pretending," tweeted one user.
