I really don't understand stuff like this. What exactly were voters expecting? Obama was never in a position to grant wishes.
His job was to stop, slow down, or restrain the stupidity, adventurism, and wrong-headedness of the Bush/Cheney regime. Having held off one disaster after another, he deserves a little more credit. Yes, there are plenty of bad things going on in the world and in the economy. What is not apparent is how much worse those things would be if the right were in charge.
Do we really want to hand things back to those who want to bomb Iran and resume supply-side economics?
