That poll couldn't possibly be anywhere close to accurate. So much of their tiny audience is anti-gun, and even if tons of gun owners get on there and vote in favor of it, do you really believe MSNBC is gonna report stuff that goes contrary to their agenda ? Hammerdown nailed it down in a previous post.
Years ago, I got a call from Gallup pollster about the Clinton impeachment. I answered their questions. Next day I get another call from them. Basically the same questions, but worded differently to elicit particular responses....... don't trust polling.
