Actually, the time to act is NOW!
We have midterm elections where 1/3rd of the Senate is elected. Its time to replace the anti-gun senators with pro-gun senators. One such critter is Paul Wellstone of Minnesota. Torricelli is another.
Unfortunately, John McStain is not due until 2004. I don't know about Bounced-Check Boxer, or Jack Reed of Rhode Island. Schumer might be due in 2002.
Too bad Clinton, Feinswine and Lieberman all won their elections on 2000, so they get to steal from us for another 4 years.
Also, it doesn't hurt to send more anti-gun Congressmen back into the private sector.
Oh, and don't rely on the NRA to do the heavy lifting. You need to research your candidates and maybe become a thorn on the side of the current anti-gun politicians. Politicians are like animals, they respond to political pain. When you and your shooting buddies come down enmasse during their town hall meetings and ask them why you should trust them to send to Washington if they don't trust you to have guns, and they stammer and stutter, they remember it.
When you do it to them twice in a row, they will tell the Brady bunch to go take a hike.
