"Cumulative Voting" Method Gaining Attention
Local ID10T writes "The AP reports on a system of voting, called 'cumulative voting,' which was just used under court order in Port Chester, NY. Under this system, voters can apportion their votes as they wish — all to one candidate, one to each candidate, or any combination. The system, which has been used in Alabama, Illinois, South Dakota, Texas, and New York, allows a political minority to gain representation if it organizes behind specific candidates. Courts are increasingly mandating cumulative voting when they deem it necessary to provide fair representation." Wikipedia notes that cumulative voting "was used to elect the Illinois House of Representatives from 1870 until its repeal in 1980," without saying why the system was abandoned.
A ranking system is the right solution.
If 50%-something would like A to win, are ok with B, but definitely don't want C, and if the 50%-something others are the exact opposite, then the best candidate should be B, not A or C where it's only down to little percentage different.
Here's a 1976 article on cumulative voting in Illinois. The writer saw it as promoting intraparty strife (creating more competition between candidates of the same party than with the candidates of the other party) and was hard for voters to understand.

Take a look at Australia. They've used IRV for over 100 years, and their house of representatives has two parties (well; one party and one 60+ year long two-member coalition that never oppose incumbent members of the other coalition-member; close enough.)
But approval voting and score voting really CAN allow third-parties a foothold. http://rangevoting.org/
