Here's the latest on the endless Minnesota recount.

With three quarters of all the ballots the Franken campaign has challenged now reviewed by the canvassing board, which we're watching via live feed, Franken is continuing the run of good math we reported he was getting yesterday.

With 339 ballots sorted, Coleman has made a net gain of 140 votes, for a pick-up rate of only about 41%. Coleman was always expected to gain votes from this phase, as the vast majority of all challenges are struck down, but his net pick-up rate seems pretty low.

The meeting is giving us a good idea of the nature of Franken's challenges, which was a very crucial piece of information that has been missing until now. A majority are attempts to not get ballots counted for Coleman, but it turns out a very good portion of them are also attempts to get votes counted for Al -- and he's doing very well on those.

The remaining mystery is what the makeup will be of the Coleman camp's challenges, and what Franken's net gain from them will be when they're sorted out. But the potential clearly exists for Franken to catch Coleman when this is over.
