It is important that we not be confused by the false choice that there are only two viewpoints on any issue. This is why it is important that there to be enough candidates in the general election to challenge common wisdom, talking points and the implicit agreement in the two-party duopoly to avoid discussing issues that actually affect us.
Instead of our current (Single vote) system, I would prefer a voting method that does not force one to vote for a compromise based on assumptions of what other voters would do.
I currently favor methods that satisfy the Favorite betrayal criterion, such as Approval voting, Relevant rating, Majority judgment or IBIFA. I would also be interested in a Condorcet-style method that satisfies or comes close to satisfying the Later-no-help criterion in order to discourage burying.
I am interested in Proportional Representation methods that do not use Single Transferable Vote.
