It's easy to scorn these folks, but mocking them does no good. In fact, a lifetime of feeling mocked by supercilious elites is what makes them prey to right wing demagoguery.
The majority can probably only cure (or modify) their ills by creating a more vibrant economy of which they get a piece, delivering health care security, and avoiding put downs. Ameliorating the real problems and letting his opponents live with the consequences seems to be the Obama tack -- trouble is, they may not let him do it.
Will he fight for his devastatingly effective program for social peace? We still don't know.
There's always a quarrel about numbers at these things. I've been to plenty of peace, women's and gay demonstrations. Some were genuinely large -- a million or more. Many were in the 100s of thousands. All thought they had more than some lowball police estimate. Just being with a lot of people who agree with you can feel like a lot.
These folks, claiming millions, seem to be right in step with the norm for demonstrators. The DC police say there were some 50-70 thousand. Not a lot for a DC rally of progressives; lots for rightwingers who aren't used to doing this.
