*sigh* There will never be a "viable third party" for a presidential election...unless you like the idea of the House of Representatives choosing the president. This is literally basic civics. A candidate must receive a majority of EC votes. It would be a very rare scenario where three viable parties are going to produce such a result. The consequence of that is that the election goes to the House. And I'm sure a major-party majority is going to pick the third-party candidate.
I realize some of you love the idea of a third party...in the abstract...but your party has zero seats in the House because you haven't done the basic party building to enable anything approaching "viable". You come out of the woodwork every four years, cast your useless vote, then effectively disappear until the next election. Lather, rinse, repeat. In every other election, you nearly always make that binary choice or do the same thing you do for president. There's a poster in THIS thread admitting he's voting R or D in all other elections but will refuse to do so for the most high level office. You leave the third-party heavy lifting to a tiny number of people who have no chance of producing local or state results that are relevant.
There are three (3) senators not affiliated with a major party and not one of them belongs to a third party. That's a fail. Any idea how many House members are third party? Out of 435 members...not one. Zero. Epic fail. You can't even elect a third-party governor, yet you come here whining about the two-party system. A system you almost universally support with the exception of a single race. And, understand, there is no EC standing in your way in ANY of those elections. So, excuse me if I view your "efforts" with total disdain.
