An executive order with regard to guns would be his undoing!
"If obamacare passes, that will be his undoing!"
"If obamacare passes, it wil be cw2!!"
Guess what, nothing happened even after SCOTUS sold us down the river. Additionally, IF (and that is a big IF) a full frontal assault on the 2nd Amendment takes place, the FIRST person to open fire on politicians (ANY politician) will result in asshats on this very site proclaiming how we need to be calm, we still have the ballot box, the shooter was wrong...etc...etc. Just look back when that commie bastard ted kennedy died, dipshits were praying for him here; that should tell you about the sentiment these days.
I suspect they will get our guns, but not in the way they expect.
