(CNN) Majorities of likely Democratic caucusgoers say they're optimistic, fired up, feminists and ... exhausted by politics. A new poll from CNN/Des Moines Register/Mediacom finds fewer soon-to-be caucus attendees consider themselves socialists than capitalists, and almost a quarter are regular Twitter users.

Three-in-five likely Iowa Democratic caucusgoers say they're fired up, especially those who are very liberal (76%), extremely enthusiastic about their first choice candidate (76%), and have locked in who they'll caucus for (71%). Likely caucus attendees who say they'll "definitely attend" rather than "probably attend" the caucus are more likely to describe themselves as "fired up" (66%).

But just as caucusgoers are fired up, they're also pretty tired. Over half (54%) say they're "exhausted by politics." Lynn Richards, a retired social worker in Iowa, says she can't turn on the TV without being bombarded by political ads.

"There are some days that I don't even turn the TV on," Richards told CNN. "You just get so sick of it! I'll be so glad when the caucuses are over. At least we'll hear a little less about it. My kids were here over the holidays and they're like, 'For crying out loud, is that all you get on TV?'"

The kicker? Richards is a precinct chair for the Democratic caucus in February. When asked if being tired of politics conflicts with being fired up about the election she said, "We've got to get people to vote or we'll be in big trouble."
