Would this voter suppression have advantaged or disadvantaged one Republican candidate over the others? Is there enough information to tell based upon pattern or geography of the problem?
Since Romny was heavily favored in San Diego, McCain was the obvious benefactor. However, I doubt he had anything to do with it. This smells of Democrat shenanigans, since their primary is open.
O.C. And San Diego were both within 2%. If the alleged 20% figure is correct, it could easily have swayed the CA results a lot.
