BRTD: Would you like to see any of the components of the Irish system used in American government?
Well their system of voting is better than FPTP, but that ain't saying much, my biggest problem with STV is the order in which ballots are counted could conceivably make a difference. Still their method of election the President is superior, even though the President is a figurehead. That I do not think would work in the US. But since Ireland has a smaller population than my state, they're not directly comparable. If any state government were to adopt an Irish-style system with the voting tweaked a bit, I could see it working. But I'd look to a different country for a model for national government.
What about Condorcet STV (forget the proper name)?
