With the U.S. Senate recount still incomplete, attorneys on both sides have already armored up for the next pitched battle: over whether to reexamine thousands of rejected absentee ballots.
With Republican U.S. Sen. Norm Coleman clinging to a reed-thin lead over DFL challenger Al Franken -- 180 votes as of Saturday night -- the issue of how and when absentee ballots should be counted has election law experts everywhere closely tracking the Minnesota recount drama.
In a race this tight, the difference could come down to clerical errors on absentee ballots or even a challenge of Minnesota's law governing such ballots.
"Campaigns over the years have challenged anything and everything," said recount expert Timothy Downs, principal author of "The Recount Primer" who has been involved in most major recounts over the years, including the biggest: Gore vs. Bush in 2000. Downs' co-author, Chris Sautter, hit the ground in Minneapolis last week as part of Franken's recount team.
On Wednesday, both sides will face off at a state Canvassing Board hearing that could prove momentous, with discussion and perhaps a ruling on whether rejected absentee ballots are in or out.
Despite the mounting number of challenges being made to the regular ballots being recounted now -- more than 1,900 as of Saturday evening, almost evenly divided between the campaigns -- experts say that most of those disputes will be easily resolved by the five-member board. As a result, the challenges may in the end make only modest changes.
But if the Canvassing Board decides to review rejected absentee ballots, many still unexamined votes could get thrown into the mix, adding far more uncertainty.
"Ultimately, if the number of rejected ballots start to make a large enough stack, it can cast some cloud over the regularly recounted ballots," said Edward Foley, who directs the election law center at Ohio State University's Mortiz Law College. Foley said the race has already taken enough twists and turns to merit its own chapter in his upcoming book on the history of disputed elections.
