Same old nonsense. Do a search of the arguments back in 2004. People were saying that Bush was going to sign an new AWB. When he made it obvious that he would do ABSOLUTELY NOTHING to push the bill, the anti-gunners called him a liar, but he got no credit from the puritans.
Then they said that we were suckers, and that the Republicans would pass one after the election. Never happened, despite the conspiratorial predications of the tinfoil hat crowd.
The fact of the matter is, this bill would have no shot in hell under a Republican Congress. But, hey, the Republicans weren't perfect, so we shot ourselves in the foot. The same "all politicians are the same" folks will be saying that the Republican Presidential candidate is "just as bad" as the Democrat soon, and they will do their damndest to make sure we have all Democrat Executive and Legislative body. You can kiss your guns goodbye if that happens.
