The number of registrered voters is IRRELEVANT in this context.

When voter participation rates are given they are given as a percentage of the total possible voter pool. This pool includes all registrered voters AND all voters who COULD obtain voter registration if they so wished to.

Also, I'm not being a jerk by pointing out factual errors. Too many well-meaning uncritically post stuff that is just factually incorrect at the most basic level. This is why so many people have a hard time taking us seriously and is a problem if we want to get through to more people.
