vk - a small technical explanation:
the prez did not sign an executive order - as janmcn noted in another post, the new immigration policy is based on "prosecutorial discretion" described in a memo by janet napolitano.

an executive order would be one way to aviod enforcing existing law and prosecutorial discretion is the way to aviod not enforcing the law by executive order.

and as far as either/any of the boys defining their position on immigration - it is no longer necessary - they can just spend the rest of the days up until the election criticizing obama for having failed the immigrant community by not embracing all of them and a meaningful resolution to the need for a revised on immigration. long-term policy
