Vote Pairing

AGain this election there are organizations arranging for vote pairing. The idea is that a third party voter in a swing state agrees to vote a major party candidate in exchange for a major party voter in a safe state voting for the third party candidate. The third party gets what it cares most about - vote totals, which provide a measure of legitimacy and the possibility of matching funds. For the major party voter, one gets the vote for your guy in a place that may matter. Difficult to enforce, for obvious reasons, but worth considering all the same.
If you have an interest, I direct you to Vote Pair.
