"Thorough investigation?" Why do we need a "thorough investigation" when we have an actual allegation of fraud? Republicans justify passing voter ID laws to prevent "voter ID fraud" that isn't even alleged to be occurring, in the name of "keeping elections honest," knowing that such laws cause a significant suppression of legitimate minority votes, votes which are overwhelmingly Democratic.
Here we have an actual allegation of fraud that involves a number of votes that dwarfs the tiny number of votes that may involve voter-ID fraud. Clearly, fast action is warranted. So let's quickly pass legislation that forces precincts where these statistical anomalies are seen to prove that their machines are hack-proof. And if no such proof is available, we don't count any votes from these precincts. The fact that such a law will overwhelmingly cause right-wing votes to not be counted is just, er, unfortunate. Yeah, that will "keep elections honest."
