That's just due to your fucked up two-party system. "Oh, look, a third party. I'm not voting for it, because that'll never help." Fucking moronic system.
Not true. The Two Party system keeps the country from being controlled by a majority government. To see how a majority government is a bad thing, one need only look at Canada.
People not voting for a third party has more to do with their own ignorance than anything set up by the system. Its because of the third parties that the Democrat and Republican parties have become the things they are today.
In America, the purpose of a third party isn't to win the national election, but to steal as many votes away from the major parties as possible. The idea is that by taking enough votes from the parties, the parties will implement their own agendas. A prime example of a third party affecting the larger was the Bull Moose Party. Though, it had the benefit of having Theodore Roosevelt as its candidate.
Currently the most succesful third party is the Libertarian Party. They haven't made strong showings in congress or the presidency, but they hold more local positions than the other 3rd parties.
Hell, the Republican Party didn't even exist before the mid-19th Century. Ever heard of the Whigs?
Of course, a two party system has its faults, but its no worse than Parliamentary governments.
Ehe. Federations are quite sucky. Giving local governments more power is more effective and nicer and can actually have a decent electoral system be preserved.
Actually, the local governments having too much power is exactly why the electoral system has these perceived problems.
Some states like Maine divide their electoral votes proportionally with the Popular Vote, while others use a winner-take-all aproach.
Also, a political revolution is defined as the overthrow of one government in exchange for another, but a rebellion is defined as open, armed, and organized resistance against a constituted government.
Does that make a failed revolution a rebellion? Does a rebellion become a revolution when it succeeds?
