They think the GOP is out of touch.
Check this out:

Michael Steele, then-chair of the Republican National Committee, criticized Obama’s stimulus plan as “a wish list from a lot of people who have been on the sidelines for years … to get a little bling, bling.” Steele, who wanted to expand the GOP’s appeal to young voters, used the expression to, in Steele’s words, “take the party to the streets,” while making the GOP more “relevant” to “urban-suburban hip-hop settings.”

In 2008, Obama took 66 percent of the 18-to-29-year-old vote, and 60 percent in 2012. To broaden the GOP’s appeal, consultants hold forums, town halls and focus groups to figure out ways to attract the youth vote. Is it the core message — low taxes, low regulation, secure boarders and strong national security — that young voters find off-putting? Is it the messenger? Former Democratic Chair Howard Dean once referred to the GOP as the “white” party.
