The Orange County Registrar of Voters has responded to suggestions of irregularities. It's full of inaccurate information and addresses the wrong issue. They assume the issue is turnout percentage but I think Jim Brulte is talking about the number of voters. Currently nationwide turnout is 4.3% higher than 2012, California turnout is 1.9% higher than 2012, and Orange County turnout is 5.0% higher. These numbers should grow some as more ballots are counted but nationwide won't hit 6% higher and California will probably be 7-8% higher. If all remaining Orange County ballots are valid they'll be up 9%. Of course SD-29 will go up too.
As of now SD-29 currently has 10% more ballots than 2012, twice the percentage of the county as a whole, and five times the percentage of the state. I assume part of the reason the county is higher than the state is because of the additional ballots in SD-29. I have no idea what the numbers are precinct by precinct by Jim Brulte is reporting that the number of ballots is up 30% in some precincts.
I'm not suggesting there's fraud, but it'd be really odd if there were precincts with 30% more votes in a state with 2% more votes. And really I just prefer people use accurate data.
