Obama is a centrist Democrat. As president, he will wage war. He will expand the domestic state, but probably not much more than McCain would. Democrats actually seem to be less profligate in some ways, as everyone always assumes they will be big spenders. Republicans can run up six trillions dollars in debt before anyone notices.
Obama will likely be a relatively pragmatic steward of the military-industrial complex, the Washington-Wall Street revolving door, the continuing erosion of the Bill of Rights, and the empire abroad. He will try to make the world love U.S. hegemony once again. He will not do too much to weaken the police state, but will rather expand it, as Bill Clinton did. He will govern like a Republican, maybe more so than Bush.
One silver lining is if he wrecks the economy, it won’t be blamed on the free market, as it is whenever a Republican uses the government to wreck the economy. If only we had had Democrat presidents since 1993, the dialogue in this country would be different when the bubble burst.
I still say, vote Barr!
