Peter Levine, the director of CIRCLE, noted in his blog today the Gallup poll that was released a few days ago showing Obama losing ground to McCain, even among youth.  Levine correctly points out that Gallup’s sample size of likely young voters was 10% when, in 2004, youth formed between 16% and 18% of the electorate.  As Levine reminds us, young voters are usually always undersampled in “likely voter” polling screens due to little or no previous voting experience.

But I thought Levine’s main point was very instructive:  if youth are sampled at their 2004 rate or one similar, McCain loses.  If they are sampled at this rate, he wins.

More directly — if youth turn out, Obama wins.  If they don’t, McCain does.  It doesn’t get much more elementary than that.

National Journal has a nice write-up on this, too.
