hi dig,
call me strange but i don't see the broad discontent. i just see the usual fox discontent affixed to the democratic president.
given the circumstances of 2008, the us has done relatively well. obamacare is an improvement on most measures. the financial markets are somewhat regulated. unemployent has decreased (even if wages aren't on fire).
it's foreign policy where things haven't gone so well. clearly intervening in the arab world didn't work. now we know not intervening doesn't work. not many options left!
