Fully on alert for pre-recount funny business, Politics in Minnesota notes that Thursday night, precisely 100 Obama/Franken votes were added from Mountain Iron's Precinct 1.

"Isn't 100 new votes for Obama and Franken in Mountain Iron Precinct One statistically impossible?," asks PIM's Sarah Janecek.

Perhaps, but I just got off the phone with Mountain Iron deputy registrar Jill Anderson, who read me the totals she called into Saint Louis County on Election Night. They exactly match what is now on the Secretary of State's website: Franken 506, Coleman 211.

Anderson said no new ballots have been "discovered" since then. That means the county probably made a recording error when transmitting the data to the state. (Haven't connected with county officials yet.)

By the way, there was a similar 100-vote error, also in Franken's favor, in Pine County. In that case, 124 votes initially was transmitted as 24.
