Ahh, okay. I see what you’re saying there with the -% in U voters above. Interesting.
In 2012, primary voters were 40% of all GOP voters.
In 2008, primary voters were 44% of all GOP voters.
In 2004, primary voters were 33% of all GOP voters.
In 2000, primary voters were 55% of all GOP voters.
So, surprisingly, 2012 featured a lower percentage of GOP primaries to general election voters than 08 or 2000. In other words, there is a GREAT deal more room to grow, even from the 2012 turnout.
