Reply #50: The trouble

with the two party system is that it weeds out too many candidates too soon.

With IRV and multiple parties the entire electorate has more options to choose from. That nullifies the issues of choosing between tweedle dum and tweedle dee only. And the coalitions can and will be formed. We have a progressive caucus in the House. I think it's no great stretch of imagination to envision Greens, Socialists, and Labor members joing the Dems and Indies there now.

Btw, Israel is a great example of what can go wrong with multi-party systems, but their system is not the only one out there. Many others do it far better. (and better than what we have here.)
