That's why he let CFR pass, and why he WILL let this pass, if need be. He has no choice. Most voters in America have no idea of the importance of gun rights. They are not Freepers or historians.
Therefore it is up to us to contact our reps in droves to prevent the passage of the bill in question, in order to stop further incrementalism upon the right to keep and bear arms.
I've never understood the thought that Republicans' supporting gun control helps them somehow. The logic seems to be that they thereby become more moderate; the problem is that they're becoming more moderate in ways that don't resonate with voters. When you have a moderate Democrat who's anti-right-to-work and pro-gun, he's less likely to vote for a pro-right-to-work, anti-gun Republican than for a pro-right-to-work, pro-gun Republican. Follow? Have some faith in the American people! Most of them aren't gun grabbers, regardless of what Dan Rather says.
That much said, I wish someone other than Chuck Baldwin had made this point. His PCP-addled mind has already come up with some psychotic theories that Bush is trying to take over the world, so his support for getting rid of this tyrannical law hurts our case by making us all seem to be wackos like him.
