one thing i've been thinking about is one issue political parties.
"our mission, once elected, is to..."
US example: thinking about medical care here: what if a political party came out and said, "we don't care about marijuana, gay marriage, federal debt, ...: only getting medical care for all.
you'll say, well that's impossible, people won't vote for them without knowing e.g. what their stance on abortion is.
but... i'm convinced those wedge issues are what keep the 2 party system intact. they'll just ruin you by pitting the other k % of people against you as mortal enemies, demonizing and alienating those voters. easy example is abortion, who probably have a lot of bright line voters.
anyway, it'd be really tough, as would any new political party in the US, would be attacked endlessly by the RepubliCrats. but, seems like an interesting thought nonetheless.
