From this morning's Earlybird:

• "The GOP-tilting Chamber of Commerce is backing Sonia Sotomayor in a letter to the Senate Judiciary Committee" sent Thursday, Politico reports. "'Her extensive experience both as a commercial litigator and as a trial judge would provide the U.S. Supreme Court with a much needed perspective on the issues that business litigants face,' wrote COC executive vice-president R. Bruce Josten."

• "EMILY's List, the Democratic fundraising powerhouse, finally weighed in on the special election to replace former Rep. Ellen Tauscher (D-Calif.), endorsing Thursday state Assemblywoman Joan Buchanan in the Sept. 1 all-party primary," Roll Call (subscription) reports.

• "The commander in chief may have no love for K Street, but his aversion to traditional lobbying tactics has combined in the public mind with the extraordinary grass-roots campaign that helped propel him to the presidency to produce a result he probably didn't foresee: a new enthusiasm for grass-roots campaigns among lobbying firms and their clients," Politico reports.
