Comedian Tommy Chong loves Bernie Sanders and has endorsed the Vermont senator for president.

Around 200 people crowded into a New Hampshire restaurant in January to see retired soccer star Abby Wambach (arms outstretched) and actress Lena Dunham (wearing the hat). Both endorsed Hillary Clinton.
"I'm embarrassed to say this, but it took me far too long to start voting," Dunham told the crowd. "I had been of legal age for more than four years before I cast my first vote in the 2008 presidential election. It's not that I didn't care, but I didn't believe that me caring mattered. It was impossible for me to comprehend that one young woman checking a box after waiting in a long line could matter on a national level."

Clinton turned to a new celebrity surrogate -- singer Demi Lovato -- in an effort to win over young women in Iowa, a state where Sanders' strength depends largely on his ability to turn out the youth vote.
In January, Clinton and Lovato drew a crowd of largely young women to the University of Iowa campus, where Lovato vouched for Clinton. After performing her hit song "Confident," Lovato said: "I don't think there's a woman more confident than Hillary Clinton."
