It would be more interesting if the results converged even a little bit to the results of credible polls. I know Obama's leading by a margin... but 95/2/3 (Dem,Rep,Ind)?
It's a neat idea with a nice implementation, but the selection bias that's going on make the polling outcome very nearly meaningless.
Yeah - either it needs to have so much volume that it's representative, or they need to include some kind of demographic to stop the results getting skewed.
As a mechanism it's an interesting idea. There are probably other twitter-ish aggregation start-up ideas that you might be able to get out of this.... e.g. send an sms/mms and it's posted as "news" for that geographic area. You could then aggregate news for relevance for a given area (e.g. local, state, national, world).
