Georgia Democratic Party chairwoman Jane Kidd has endorsed Barack Obama for president, giving the Illinois senator another Georgia superdelegate vote.

Kidd, who had remained neutral in the race between Obama and U.S. Sen. Hillary Clinton of New York, said Wednesday that she was impressed with Obama's grassroots organizing in Georgia.

"In Georgia, we're making grassroots voter contact our top priority in 2008, and I'm convinced that Senator Obama shares our dedication to neighbor-to-neighbor contact," Kidd said. "I strongly believe that having Senator Obama as our nominee puts Georgia into play, and I know that, as the nominee, he will invest in our efforts to turn Georgia blue this year."

Obama now has the support of seven of Georgia's 13 superdelegates: U.S. Reps. David Scott, John Lewis, John Barrow, Sanford Bishop and Hank Johnson, along with DNC member Mary Long, who endorsed Obama on Tuesday. Clinton has the support of Labor Commissioner Michael Thurmond and DNC members Carole Dabbs and Lonnie Plott.

Remaining undecided are former President Jimmy Carter, U.S. Rep. Jim Marshall and DNC member Richard Ray. A spokeswoman for Carter told the Atlanta Journal-Constitution that he will remain neutral. Ray and Marshall were not immediately available for comment Wednesday.
