I too, would like to see a good strong viable 3rd party with true conservative values, because the Republicans have gotten watered down. But, it is a monkey wrench in the works in itself.
When I was in college, there would be a dozen to 15 folks running for school president. Out of those 12-15, the black interest groups on campus would only put up one cantidate. This would ensure that the lone black cantitidate would get 99% of the black vote, plus some of the others. The 11-14 cantidates left would have the votes so split up, none of them could come even close to the votes garnered by the black cantidate. They did it year after year. That is what has happened to the Republican voting block. We have Repubs, Independents, Teaparty, and Libertarians, to mention a few, that split the vote. If there is another liberal party besides the democrates, I have not heard of them, and their voting block is irrelivent.
The only way a conservative third party will stand a chance is if the Democrat vote can be split up with other parties also.
