I was on the Gun Owners of America website looking at the ratings and doing a count. I counted C rating or better as pro gun, D or below as anti-gun. And I don't guarantee the accuracy of my count. [&:]
House:209 pro gun, 192 anti-gun, 23 not rated
House requires 217 votes for a majority
Senate: 43 pro gun, 53 anti-gun, 4 not rated. Of those 4 is Jim Webb who can be added to the pro gun count, so make it 44-53-3. Neither side can break a filibuster.
It depends on which way those unrated - not to mention the marginal C rated - Congressmen swing.
I wish the GAO site listed the Senators and Reps by party, but it doesn't. Look for your Congressmen on the list and get after 'em.
