Montgomery, Ala. ? Democratic Gov. Don Siegelman and Republican challenger Bob Riley both claimed victory in the Alabama governor’s race Wednesday, with Siegelman charging that a GOP-dominated county altered its vote totals in the middle of the night.

Congressional contests in Colorado, Louisiana, New York and Texas were still not settled, and the governor’s races in Arizona and Oregon weren’t decided until late Wednesday afternoon.

In Alabama, election officials in Baldwin County late Tuesday distributed figures that showed Siegelman with 19,070 votes, enough to give him the victory in the unofficial statewide count.

But on Wednesday, the county certified results that gave Siegelman 12,736 votes while leaving Riley’s numbers unchanged. That erased the governor’s thin margin in the statewide count and put the GOP congressman ahead by 3,195 votes out of 1.3 million cast.

Probate Judge Adrian Johns blamed a software glitch for the earlier figures.

In the Arizona governor’s race, Democrat Janet Napolitano eked out a narrow win over Republican Matt Salmon. With all precincts reporting, Napolitano, the state attorney general, had 472,197 votes, or 47 percent, and Salmon, a former congressman, had 446,913 votes, or 44 percent.

In Oregon, Democrat Ted Kulongoski defeated Republican Kevin Mannix in the state’s tightest governor race in years. With 92 percent of the vote counted, Kulongoski had 561,765 votes, or 48 percent, to 541,937 votes, or 47 percent, for Mannix.

In Vermont, the governor’s race was all but decided when Democratic Lt. Gov. Doug Racine conceded to Republican state Treasurer Jim Douglas. Douglas held a 6,000-vote lead but failed to win the 50 percent needed to avoid having the election thrown to the Legislature in January. But Racine said he would not contest the outcome.

In New York, the race between Rep. Felix Grucci and Democrat Tim Bishop hinged on about 6,000 absentee ballots, which will be counted Monday. A congressional race in Colorado between Republican Bob Beauprez and Democrat Mike Feeley also was too close to call.

Texas Republican Rep. Henry Bonilla was re-elected with a 4,900-vote margin over Democrat Henry Cuellar. The outcome was uncertain until late Wednesday because of slow counting in Bexar County.
