I've moved slowly to the side of proportional representation.   It just seemed like a step too far for me because it would take massive structural changes in the election process.     

I fully support open primaries.    I'd be fine with 'ranked' voting which is a much better way of determining voter choice.  I'd be fine with multiple candidates in the general election, a process that also suites ranked voting system.   (puts a value on your second and third choices, so it's not just a win/lose result)

Maybe there are other structures that would give minority voices true representation in legislation.    A minority deserves to be represent itself, free of the 'privilege' that a Party may or may not grant to them.
