@shewolfnm,
In some ways what we have resembles a one-party system or at best a 1.5-party system, but in numerous other ways the democrat party is far worse.
We need a voters' bill of rights, starting with runoff elections for all public offices; nobody should ever hold any public office with less than 50% of the vote and nobody should ever fear to vote their first choice, at least for a first candidate. THAT would allow some third party to rise up and replace one of the two major parties, at least at state or local levels.
