Obama needs to simply, very publicly, extend what he's already stated, but more clearly as it relates to actual negotiations coming up:
Stand up and say "We will not begin to negotiate until the debt ceiling is raised."
and simply stick with it. what the hell would they be able to do against such a simple strategy? Send the country into a freefall with this clearly stated a month early?
The last time the republicans held this hostage, S&P lowered our fucking credit rating. No way they don't flinch this time.
