Vote Swapping is an idea that appears (note my political ignorance) to have come into existence during this presidential election, as a result of the Internet and the three-cornered Bush-Gore-Nader race. There are several sites that have sprung up to facilitate vote swapping, aimed at liberal voters. The goal is to put Gore in office, while simultaneously getting Nader the 5% of votes needed to receive federal funding for the 2004 election. This is accomplished, in theory, by strategically distributing votes by state: if you live in a state where Al Gore is already strong, you swap your vote for Gore with someone from a state where he is weak, and instead vote for Ralph Nader... While your opposite number, theoretically a Nader supporter, votes for Gore.

The most streamlined of these sites that I saw in my five-minute perusal was http://www.winwincampaign.org.
