Not to mention that this is hardly a sign of Muslim radicalism. Egyptians are getting increasingly tired of the fact that Israel continues to be the world's biggest douche. Quite frankly, they are massive instigators, but always get away with it because they are daddy's (the US) favorite.
It has VERY little to do with them being Muslim. It has to do with the fact that Israel killed a bunch of Egyptian police and military personnel while chasing Palestinians on Egypt's side of the border, where they so obviously had no right to be.
It'll be close, but Romney has the momentum.
