MINNEAPOLIS (Reuters) - Democrat Al Franken, a satirist turned politician, was declared the winner of a Senate seat in Minnesota on Tuesday, clearing the way for President Barack Obama's party to secure a critical 60-seat majority in the Senate.

Ending one of the longest Senate races ever, the Minnesota Supreme Court unanimously rejected each of Republican Norm Coleman's five legal arguments that an earlier recount of the November 4 vote had been unfair. Coleman quickly conceded.
