I'm gonna go out on a limb here and make a prediction of what's going to happen.
The deadline to raise the debt ceiling is August 2. Now I don't know if it will go right up to the wire on the very last day, but perhaps it will. For sure it will extend into the next two weeks and we will all hear about how obama this and republicans that, and the world is falling apart.
The Republicans and obama will be jockeying with one another trying to arrange the best possible deal. The media will get more and more crazed as the time goes on and we get close to the deadline. The stock market will fall by a few hundred points and fear mongering will reach all-time highs. Afterall, the sky is falling. Then at the last moment, the "heroic" politicians in congress will step in and save the day by reaching an agreement, and the media will have a big celebratory orgy, and the stock market will rally like Obama just saved the world from extinction, as they just escaped having the US AAA credit rating lowered by Standard and Poor and Moody's at the very last minute. And the final deal will include a raise of the debt ceiling coupled with a cut in spending and potentially some type of tax reform but what that will be remains to be seen. But the main portion of the "deal" is legislated cuts in spending coupled to debt ceiling increase.
Take it to the bank. I highly doubt they will let us default, it would be a disaster for the economy to have our credit rating lowered. Everyone says the republicans watch out for the rich, well if that's the case, they know that the pockets of every rich person will be hit hard if the stock market falls, and it certainly will if US credit rating is lowered. Of course, due to all the "fear" and "uncertainty" it will definitely fall in the leadup to any deal.
