Vote for the Socialist Labor Party!
No, not really. Besides the ideological problems, there's the small fact that it hasn't bothered to nominate a presidential candidate since 1976. But I must admit I admire one plank in its program:
The Socialist Labor platform called for abolishing the presidency, and party electors were instructed to vote "no president" in the comet-striking-earth chance that the SLP carried a state.
That's from Bill Kauffman's thoughtful review of Daniel J. Flynn's A Conservative History of the American Left. There's more to the article than entertaining asides about the presidential platforms of semi-syndicalist sects; read the whole thing here.
