Regarding these rallies, even as a strong supporter of Obama over McCain, I'm surprised by the numbers who go - I'm not sure I'd go to one nearby. They seem like fairly empty exercises to me, repeating the marketing slogans. I'll speak out for Obama, but watching him give the 'change we can believe in' speech doesn't do much for me. But I might go just to 'show support' and see the other supporters a bit.
I think more issue-oriented people can find the populism techniques - the mob energy - important to winning an election sort of disconcerting, even with candidates we support, if nothing else just because it's clear how that same approach can be used by candidates with terrible positions, and worrisome how little issue-oriented arguments are in influencing the opinions of so many people.
I'd considered starting a thread on the topic of 'things wrong about the 2008 election even if the right guy wins', but one point is how nothing has been done to fix the issue of money haveing too much a role, we just got lucky to have 'our guy' be better able to raise more this time; it's an issue that will bite us as long as big money has that lever in its hands. Another is how the trivial (lipstick on a pig, 'socialist') *still* dominate far too much.
