We became a global superpower under a two party system. We passed the New Deal under a two party system.
It’s not the number of parties holding us back from greatness, and the suggestion that it is is what gets a fringe group of people to vote for Ralph Nader, and ultimately hand the country to George W Bush.
Republican lunatics absolutely love their party right now. The problem is that democrats keep voting for moderates in the primaries because they think that voting for Bernie Sanders will wind up with us losing the general election… As if Republicans don’t already call Obama, Hillary, and Biden socialists and communists.
