I might be crazy, but I think I may have just figured out why the Repubs are dragging out the primary.
Run with me on this one. GOP strategy goes something like this… Step one: make new restrictive voter registration/ID laws. Step two: Purge voter registration rolls under the pretense of preventing voter fraud. Step three: encourage GOP voters to register and vote by holding contested primaries in each swing state - Ohio. Pennsylvania. Florida. Michigan. Illinois.
This gives them the chance to work out any voting kinks months ahead of the general election. So come November the Republican voters are squared away and ready to vote, while there are going to be a lot of frustrated and confused Democrats who will either not be able to register, find themselves mysteriously unregistered, or otherwise not be able to vote. All because they skipped the Democratic primary with Obama running unopposed.
