We have lots of frivolous and irrelevant small political parties--whether you number them third, fourth, fifth, or whatever.
We're discussing the possibility of a third Major Party developing---one that can actually win statehouse seats, congressional seats, and maybe a serious run at the White House as a contender, not a spoiler.
That would be very hard to do, but some are saying that the time is coming for it.
I'm skeptical, but I'd love a serious, viable party to the left [economically more than socially] of the centrist Democrats.
I just don't expect to see one, because even with enthusiasm from the ideological standpoint, from the financing standpoint, it's a huge task.
