A lot of republicans have held back, but Cheney (he simply can't control his pie hole) and Mitt went there. It's highly unpatriotic and brazen (stupid) for Mitt to criticize Obama on the drone.
First of all, there is a lot mystery about what happened. Is it out of the realm of possibilities that the "captured" drone is gathering information right where it is? Most important, it's a classified intelligence matter involving national security and a volatile Iran, and Mitt is using the drone as political fodder in a desperate attempt to win an election that's slipping away from him. Mitt's comments are reprehensible and dangerous.
