IOWA CITY, Iowa — Hillary Clinton has a lot of celebrity pals on her side, like actress Lena Dunham and singers Katy Perry or Demi Lovato, the latter of whom belted out hits at a campaign concert at the University of Iowa.
It's a play to help the former secretary of state connect with younger voters. But so far, the star power isn't swaying the college set. Many say they prefer her rumpled 74-year-old rival, Vermont Sen. Bernie Sanders, regardless of whether he got star power behind him or not.
"Bernie appeals more to my cool," said Alex Bare, 19, a University of Iowa student who plans to caucus for Sanders, but said he likes Clinton and came for the free concert in Iowa City Thursday. "He refuses to take money from super PACs. That's a really bold move and for me, that makes him cool."
The push for younger voters comes amid an intensifying battle for the Democratic nomination. While Clinton and Sanders are locked in a tight race in Iowa, and Clinton has held the lead nationally, Sanders has a clear advantage among younger voters. A recent Des Moines Register/Bloomberg Politics Iowa poll forecast that Sanders will have 59 percent of Democratic caucus-goers 45 and under, compared to the 27 percent expected to back Clinton. And in the latest CBS News/New York Times poll Sanders led 60 percent to 31 percent among Democratic primary voters under 45.
"He has the hipster vote," said Erin Kelleher, 26, a graduate student at the University of Iowa, who said she was deciding between Clinton and Sanders. But she said the Lovato show wouldn't sway her because "I don't care about the celebrities."
Sanders has collected some celebrity buddies too. Actress Susan Sarandon and actor Justin Long are appearing at Sanders rallies in Iowa ahead of the Feb. 1 caucus. The campaign also has a number of celebrities doing media outreach on Sanders' behalf, including hip hop artist Killer Mike and musicians from the bands Foster the People and Vampire Weekend. But Sanders is drawing big student crowds without them on the bill.
It's not that the students were negative about Clinton — they simply like what Sanders has to offer more. They are packing his rallies by the thousands because they like his push for free tuition at public universities and his long record on liberal issues. They like that he doesn't take money from political action committees. They even dig his rolled-up shirt-sleeves and his grumpy grandpa demeanor.
Most of all, they love the slogan: "Feel the Bern."
"Bernie gets me stoked," said Ian Wold, 20, a junior at the University of Iowa who plans to vote for Sanders in the state's kick-off caucus.
The fight for younger voters harkens back to the 2008 race, when Clinton lost the youth vote to President Barack Obama. While younger voters tend to be less reliable participants, they can make all the difference in a close race. In addition, young enthusiasm helps a candidate project momentum.
About 1,700 students came to hear Lovato and Clinton Thursday. Backed by a small band, Lovato performed several songs, including her hit "Confident," after which she said "I don't think there's a woman more confident than Hillary Clinton."
Clinton then came on stage and spoke for about five minutes, calling Lovato an "extraordinary young woman" and urging the students to caucus. She drew enthusiastic applause pledging to fight for equal rights and to "take on those big special interests."
Earlier in the day, Clinton held an event at Simpson College in Indianola, Iowa. The room packed with more than 500 people was largely older. Hannah Friesen, a 20-year-old student who said she was undecided, said that when Sanders came to campus, "a ton" of students attended and some "made their own shirts."
Some students at the University of Iowa and at the concert were Clinton fans. Austin Graber, 22, said he thought Clinton was "the most qualified." And Lauren Ellbogen, 18, said she'd be working at the caucuses for Clinton and said she didn't think Sanders was "realistic."
Huge numbers of young people turned out to rallies for Sanders on college campuses in eastern Iowa over the weekend. Over 2,000 people came to hear Sanders at Luther College in Decorah Sunday morning. Decked out in "Feel the Bern" shirts, students screamed and cheered when Sanders touted his lack of a super PAC and pledged to provide free tuition at public universities. The crowds chanted: "Bernie, Bernie, Bernie," and frequently yelled "We love you Bernie."
Celebrities have been campaigning for Hillary for months. Wearing an American flag cape and a Clinton campaign pin, pop starlet Katy Perry performed at a Clinton rally in Des Moines in October. Actress Lena Dunham toured Iowa and New Hampshire and did events in Boston and Chicago for Clinton this month.
Many students said the Lovato concert was a good move for Clinton, but they weren't all convinced. Jen Moulton, 18, who leans to Sanders, said the concert was "kind of cool, but it comes off like she's trying really hard."
