Which issue?

[The_Rorschach]

Come on Kelly, this isn't terribly hard. The question is "Do any of you see such an issue troubling the two-party system in the near future?" In order for a two party system to be 'troubled' there must be some threat, and in this context, the threat outlined by Kevin is a three party system.

"Third parties don't necessarily have to raise themselves to the prominance of something like the main two parties to have an influence. All they need is an important, relevant issue to make part of their platform"

Stupidity. What they need is to garner a voter base, which in my opinion, will never occour. Americans are politically disinterested, they don't support the two institutions already emplaced, why the hell would they suddenly be startled from their stupor for a third party? Issues are irrelevent at this point in time, and will continue to be irrelevent until they begin infringing upon the fat happy lives of the average citizen -by which time it will be far too late.
