Democratic voters didn't turn out, and Coakley lost. She should have run a better campaign, and the DNC and the DSCC should have gotten behind her--this was a crucial race, and they totally dropped the ball. I think the suggestion that there was concerted fraud because you've found some numbers to massage is actually counter-productive: Democrats need to read this as a canary-in-the-coal-mine moment and get their shit together.

On edit: you're still not linking to the actual results you're citing--just giving us the general neighborhood and saying "go find it." Please link to the actual numbers you're using.
