No he wouldn't, not anymore. The MSM would praise him to the hilt.
People need to step back from their blind adulation of the Paul clan and think: "What possible advantage could the President reap from a drone strike in the US as opposed to a much cleaner and quieter conventional assassination? What political gain could possibly outweigh the political cost of such a clumsy and stupid action?"
Why do we use drones in the first place? Because they are a substitute for lethal boots on the ground in places where it is too expensive or politically prohibitive to establish such a ground presence.
The President has boots on the ground on every square inch of US soil if he needs them.
