Perhaps I shouldn’t have formally disaffiliated myself from all political parties. Dutch:

I don’t really vote any more, but I keep my Repub voter registration. The reason is this—the single strongest factor in vote results is the party breakdown of voter registrations. When a precinct has 65% Repub voters registered, but the Dem wins the precinct with 55%, the game is obvious, for someone who is actually paying attention and knows how things work.

The relationship between voter registration percentages, at the precinct level, and actual vote tally percentages was tight, very tight, until 2008. That’s when precincts tallying 65% or 70% Republican registrations started going for the Dem candidate 50% or more. There’s your break, and that is where Dominion entered the picture, 2008.

This seems all too plausible, but I would like to see the documentation.
