What little I know about EO's is there are two ways to look at them.

1 - That most are unconstitutional, not just BHO's but all since at least back to Lincoln, probably further.

2 - Since EO's have never been clearly defined or challenged by SCOTUS, the other side of the coin is they're all constitutional and the power of the EO is unlimited.

Obama is not the first to do something VERY controversial through EO. But this one seems a bit dumb, even for BHO. Congress has been battling this one for over a decade, and to have one person just circumvent the entire legislative process on an issue that is so tied to the legislative process.
