If the Prez tried issuing an E.O. which sought to overturn a state law that had not been deemed unconstitutional, the political blowback would be enormous.
The blowback would begin with the Governor publically denouncing the EO, backed up by his majority in the state assembly, thus guaranteeing the reelection of all who did so.
Then it would spread outward to other states who would pass resolutions basically telling Obama to go bleep himself for his overreaching arrogance.
The WH won’t try anything that rash. They got their @sses handed to them when Obama’s gungrabbing bill went down in flames.
More subtle: Obamacare will turn family doctors into government snitches who note the attitudes of citizens who refuse to answer questions concerning guns.
Uh... state voter I.D. laws?
