Franken's lead grew by a few votes on Tuesday when the state Canvassing Board finished allocating thousands of ballots that had been held up due to candidate challenges.
Coleman's hopes now ride on a pool of uncounted absentee ballots that will be opened before next week. The size of that pile is in dispute but it is thought to be around 1,350. Coleman's campaign wants to add 650 more to the stack.
Even if the board declares a winner next week, the race won't be over. The losing party is expected to challenge the outcome in court.
