Petition to preserve the independence of the US Corporation for Public Broadcasting. By Common Cause, the people who brought you campaign finance reform. Non-partisan.
Petition against the anti-gay marriage amendment. By MoveOn.org, who started the on-line "Censure Clinton and move on campaign". A liberal organization with Democratic party sympathies. Since I'm writing about politics, let me point out that there are solid conservative and libertarian reasons to oppose this admendment: in particular because it brings Federal legislation to an area never before covered by Federal law and because it brings the government into the bedroom.
