Also, it appears there may well be large numbers of curiousity seekers coming to his rallies, who may or may not be showing up to vote for him after the fact.

The whole rally phenomenon is like showing up to see the Grateful Dead or the Rolling Stones, IMO.

Rather like the caucus vs primary argument. So few people actually show up to caucus when compared to the number of people who actually show up to vote, that it even skews the popular vote totals.

In reality, Obama has the biggest rallies, and has won the small caucus states, hands down.

But Clinton wins the big states with huge populations who vote in primaries.

There won't be any caucuses in November, which I think still gives Clinton a slight edge over Obama in the general, as it stands today.

Of course, if today's status quo doesn't change (ie Obama ahead of Clinton by a nose), and everything goes according to the Obama game plan rather than the Clinton game plan in the remaining primaries, Obama keeps the edge.

But I think his support has always been shallow, except in the African American community. There may be a backlash brewing among young voters, who are reportedly tiring of being labelled as all being in Obama's camp. The Clinton youth vote is getting better organized and more vocal.
