"You may vote the primary ballot of the political party with which you currently wish to be affiliated. If you voted the primary ballot of a different political party in 2005 or 2006, you will complete a statement at your polling place confirming the change in your political party affiliation." http://www.sos.state.oh.us/sos/PublicAffairs/VoterInfoGuide.aspx?Section=15
