On Meet The Press this morning, Ralph Nader, perennial third-party candidate, said he's running [1] for president of the United States. Launching his third bid in as many races, Nader said,

Dissent is the mother of ascent. And in that context, I have decided to run for president.

Shunning the notion that he serves as nothing but a spoiler for a Democratic party victory, Nader shot back,

Not a chance. If the Democrats can’t landslide the Republicans this year, they ought to just pack up, close down, and re-emerge in a different form.

How will this development affect the race? Could Nader's entry bait other third-party runs? Is Bloomberg on Nader's speed dial? Though many nations have political landscapes that support lots of political parties, can our solidly binary system support triangulation by a third — or does the other candidate stand to be a mistress, a spoiler distracting voters from working on their relationship with their party?
