I was at Presiding Judge Training last night (in Ohio) and we were reviewing form 10 X--Change of Party Registration Form.  The form states "I (name of person Challenged) of (Address) hereby state, under penalty of election falsification, that I desire to be affiliated with and that I support the principles of the (Designate Democrat or Republican) party and wish to cast a ballot in the party's primary election this year."  It is left up to the Poll Workers to decide if the individual gets to change their party affiliation or not.  I'm new to this arena--anyone have any experience with people switching party allegiance in a primary in order to vote in such a way that is beneficial to their original party?  Has anyone ever been denied the opportunity to switch parties at a primary election?  Our trainer would not even give us an example of when a Poll Worker would approve or deny this request.  Falsely switching parties is a 5th degree felony.
