Some poll findings Obama won't be too happy with: Young people don't want to vote as much as they used to and Floridians aren't too fond of health care. Here's our guide to today's polls and why they matter.

Findings: Young people are losing interest in voting. Just 58 percent of voters 18 to 29 years old said they are "definitely likely to vote" this November, down from 78 percent in a poll taken in October ahead of the 2008 election, and 81 percent in 2004.

Pollster: Gallup

Methodology: 2,803 registered voters in the 18-to-29 age group were called by phone between May 1 through July 10 as part of Gallup's larger national poll. The margin of error for the subgroup is +/-2 percentage points.

Why it matters: Young people were all about Obama in 2008 and he needs them again now, but the lower enthusiasm for his giving him a second term could cost him votes for his re-election.

Caveat: Young people don't really get excited about elections until the fall. In the last two election cycles the amount of people in the youngest demographic who said they would vote went up between June and and October — in 2004 it jumped 20 percentage points and in 2008 it jumped 9. Even so, young people don't trust young people when they say they'll "absolutely" vote. Of those 78 percent who said they were definitely voting, many didn't. The turnout rate for 18-to-24 year olds in in 2008 was 49 percent, according to the U.S. Census Bureau.
