Norm Coleman’s attorneys vowed to go to court to make up the ground the incumbent Republican lost today after more than 900 absentee ballots that had been mistakenly rejected were tallied, increasing Democratic challenger Al Franken’s lead for Coleman’s U.S. Senate seat to 225. “We’ll take whatever legal action … to remedy this artificial lead,” said Coleman recount attorney Fritz Knaak.

“I’ve had better days,” Knaak conceded. “The numbers are what they are.” But he repeated that the “process was broken” and predicted that “the election will still be called in Coleman’s favor.”

That will happen, Coleman attorney Tony Trimble said, when hundreds of absentee ballots that the campaign still wants reviewed are opened and counted. “We’re still trying to ferret out for counting these 600 ballots,” he said, adding that fixing more than 100 allegedly double-counted ballots in Minneapolis would help Coleman as well.

Secretary of State Mark Ritchie said he expected that the State Canvassing Board would declare a result of the election on Monday — a result that seems all but certain to favor Franken.

“I’m also not happy that the two campaigns had the right to veto” once-rejected absentee ballots that local officials, on review, determined should be counted — referring to a controversial Dec. 18 state Supreme Court ruling that only absentee ballots that election officials and campaign representatives could agree upon should be counted.
