By November 2010, this economy will be humming along and the Dems will be running on the platform "We finally were able to pull the American Economy out of the GW Bush Republican nosedive." People and companies will find their health insurance premiums going down due to government competition ... and their take-home pay increasing, even if just a little!
Youth is easily disappointed. The youth vote is a wildcard and may be a joker. Neither party should count on it in the 2010 elections. I don't see youth showing up for Leonard Boswell or his Republican opponent. I do see an angry electorate taking their hostility out on incumbents.
