This is exactly why I asked the question because I feared that only republicans would show up on the ballot. The thing is that republicans seem so against the proposition it confuses me. According to
Wikipedia Louisiana has had the system since 1978 although California and Washington just change the system in 2010, so I am not sure if there is not enough data if it can be successful or not. I might just leave it blank on the ballot.
Did you notice any changes in this election then previous elections?
