Obama/Biden vs. McCain/Palin Crowds

Is there anyone out there comparing the crowds of Obama/Biden vs. McCain/Palin? I just remember early on in the primary, crowd size was one of the media’s justification of Obama’s coronation as Reverend Most High. So, now with Palin pulling in thousands at rallies, I’m not hearing much anymore about Obama crowd size? Now, I’m not trying to say that crowd size is any measure of how the election is going to go, but it does show us a little. More than anything, I’m curious to know the comparisons lately.
