How many "Limbaugh Democrats" charged their registration back to Republican after April 22?

That might be one way to determine how many "Operation Chaos" voters there were in PA on 4/22. If a lot of people changed their registration back to GOP after the primary, that would seem to suggest Limbaugh footsoldiers.

1. The rules are different in November

While what you said is true, and it would be interesting... Many of those voting scabs know that they can remain registered Dems and still vote straight repuke in November. They wouldn't have to switch back until the next repuke primary.
