Neither King County nor the Republican party could confirm the hand recount results on Tuesday night. But if the Democrats' analysis is correct, it's a stunning reversal in the gubernatorial race, which has been hotly contested ever since election day.

Republican Dino Rossi won the first count by 261 votes and won a machine recount by 42 votes, out of 2.9 million ballots cast.

"We're confident Christine Gregoire has been elected the governor of the state of Washington," Democratic Chairman Paul Berendt said. "I believe Dino Rossi should concede."

Berendt and Democratic party officials reached their conclusion after crunching numbers supplied by King County. The county has finished tallying its 900,000 ballots, but election officials said they still need to reconcile differences in the precinct totals.

"We are not releasing our results until tomorrow at 3:30 p.m.," said King County Elections spokeswoman Bobbie Egan, who confirmed that both parties received the recount data Tuesday.

Rossi spokeswoman Mary Lane said Republicans are also looking at the data but had not drawn any conclusions. "It's just too close to call," she said.

The Rossi camp has said that if it lost the third count it might challenge the election in court, and Republicans were already preparing for a possible legal challenge. Gregoire had promised to concede if she lost the recount.

Berendt's contention that the race had been decided came one day before the state Supreme Court was to hear arguments on whether King County - which is solidly Democratic - should be allowed to add to its recount 700-plus ballots that weren't counted originally because of mistakes made by county election workers.

A Pierce County judge on Friday granted the state Republican Party's motion for a temporary restraining order to stop King County from counting those newly discovered ballots. King County, the state Democratic Party and the Secretary of State appealed the case to the state Supreme Court.

Seven justices will hear the case. Three of the regular nine justices are out of town on previously scheduled trips, and one temporary judge will join the court.

About 350 people gathered Tuesday in front of the Supreme Court to show support for Rossi at a rally sponsored by KVI-AM, a conservative talk-radio station.

The crowd chanted "No new votes!" and "No more fraud!" They held signs saying "Welcome to Ukraine" and wore orange, a tribute to the signature color of demonstrators in Ukraine who protested a fraud-marred election there.
