The war that lasts another 6 months, then another 6

MoveOn is a political action committee that is antiwar, pro-environment and active on progressive issues. They make it easy to send email to your Congresscritters and they buy advertising to help educate Americans on important issues. They endorsed Obama this year by popular demand (landslide) from a majority of their members, even though they normally don't pick a candidate. And best of all, they'd rather have your signature on petitions than your money.
