The Minnesota Supreme Court says he was elected U.S. senator. By 312 votes.
Republican Gov. Tim Pawlenty did tell CNN over the weekend that he was inclined to sign the election certificate if the Supreme Court ruled for Franken. But he hedged a bit, still, saying he'd issue certificate if ordered. The Supreme Court said Franken was "entitled" to receive the certificate, but didn't explicitly order Pawlenty to issue it..
UPDATE: Around 3 p.m., Norm Coleman conceded. The secretary of state says he will sign the election certificate once Pawlenty does. There's a 10-day period in which to seek a rehearing of a Supreme Court decision, but it looks like you can finally turn out the lights on Norm Coleman.
