You can vote for ANYONE in the GENERAL regardless of party you are registered to.
In the primary you MUST vote along party line you are registered to..as an Independent, there wasn't anyone representing the party therefore I was turned away. Many others were disenfranchised too.
In all honesty, I was told as an Indy, I could vote for anyone..they just failed to mention that those aren't the rules for the primary..as I mentioned in my original confession, I wasn't the only one walking out with NO 'I voted' sticker..I received bad verbal information and didn't double-check..so did others..but it's my fault for not checking.
So to answer your question..you can't.
