Barack Obama's Magic Number

According to a USA Today poll, Barack Obama now has the support of 50 % of respondents in a head to head match up with John McCain.

Pundits have been saying he couldn't get to the 50% mark (while ignoring that John McCain has not reached that mark). Well, here it is, 50 - 43.

Rasmussen has Obama at 51 %, when they include "leaners," to McCain's 45 %.
