Having seen how the MSM lies about crowd sizes, I suspect that this number of 800 people is an over-estimate --- it wouldn't surprise me to find out that there were only 400 or even less attendees there.
Granting even 800 people, that's still a very, very small turnout considering that Senator "Coke-head" Obama is supposedly a leading contender for next President of the United States.
looks like we were thinking along the same lines ;-)
