Is it not suspicious that Florida and Ohio-Michigan are places that "repeatedly" have voting problems?

Notice the only thing that they all have in common is that they are screwed up on the DEMOCRATS side, the republicans seem to know how to use the voting machines and to cast a ballot, hell even with the changing of the primary dates they still have their delegates seated. The democrats could learn a voting lesson from these Republican foes, if not, then I am sure they will lose more elections and claim voter disenfranchisement.
