The Dems will win on health insurance reform, and over the next 25 years will argue with the Republicans over various important improvements (which the Repubs will denounce as "expansion of government power" and "employing more and more bureaucrats" or some such).
In the medium- to-long term, say 25 or so years out, the Democrats will in fact have come to take their rule for granted. They will propose foolish ideas and will be taken down over the ensuing 15-25 years, when the latest iteration of the conservative movement again captures political power.
I'm inexplicably upbeat and positive about tonight's BHO speech. I saw a few minutes of his Cincinnati speech, and had the experience of thinking I was re-connecting with an old, dear friend after a summer apart. Weird, yeah.
Any hoo, I'm sure I'll find more than adequate grounds for pessimism and gloom shortly. Do not be alarmed!
