I wonder if such a platform might have something of a chance, say, 30 years from now?
I think it could.
I think the time is ripe for a new party with such a platform, however it will take time (I don't know about 30 years though, might could do it in less time).
I think the time is ripe for a new party for two reasons :
1)Many voters on both sides feel the two parties are out of touch with them.
2)Voter turnout is pathetically low. A new party that could generate a lot of interest could make a lot of headway.
Hard to say, but it would be irrelevant to me personally. I will be drooling in some old folks home by then if I am still breathing.
The time to start is now, it may take a long time.
