Senator Johnson is on our side also.
This is an excerpt of an Email I recieved after contacting him.
....As your Senator, I believe it is my primary responsibility to uphold the Constitution and the Second Amendment is no exception. I will continue to strongly support our Second Amendment rights. One of the bills I have chosen to cosponsor regarding the Second Amendment is S. 570 introduced by Senator Jon Tester (D-MT) on March 14, 2011. This bill would prohibit the Department of Justice from tracking and cataloguing the purchases of multiple rifles and shotguns.
But, I don't think this is a reason to "stand down" or relax. We need to keep our allies aware that we are watching, and keep pressure on the others too.
Sen. Baldwin is probably a lost cause, she doesn't even have an Email contact listed anywhere.
The real battle is for the "fence sitters" who can be swayed to one side or the other by our involvement.
