There is one issue that brings the Democratic and Republican parties together like no other: their shared commitment to maintaining closed primaries.
In three open primaries states - Idaho, South Carolina and Wyoming - Republicans have filed suit and/or introduced legislation to eliminate open primaries and require voters to join a party.
After Californians passed Proposition 14 in June, party leaders sued to overturn it. Democrat Party leaders in both New York City and Kentucky derided open primaries as unAmerican - the leader of the Kentucky Senate, Democrat Julian Carroll, actually told Independent Kentucky founder Michael Lewis to give up his quest for open primaries or "move to another country."
