You own second citation contains the following passage:
>ridges removed the five votes from the final count: four for Rossi and one for Ruth Bennett.[32] No evidence was brought before the court of any of the illegal votes benefitted Gregoire.[32] The final margin of victory for Gregoire over Rossi was 133 votes.[33] Rossi did not appeal to the state Supreme Court[34] and the Washington State Republican party settled the case after paying $15,000 in court costs to the Democrats.[35]
Judge Bridges' ruling was seen as a comprehensive defeat for Rossi. The judge admitted nearly every piece of evidence the Republican Party offered and then wrote a thorough, tough opinion rejecting the Republicans' claims (while criticizing the administration of the election, particularly in King County); Rossi was left with very little legal ground for a successful appeal. After receiving such a negative verdict, Rossi declined to appeal to the State Supreme Court, claiming that the political makeup of the Court would make it impossible for him to win, thereby ending all legal challenges to the election of Gregoire as the Governor of Washington
The plaintiffs, the Washington Republican party wasn't able to provide any evidence that improperly cast ballots disproportionately went to the winner of the election. Additionally the judge noted that many of the "illegal ballots" were simply improperly cast provisional ballots. That means that people casting them weren't trying to commit a crime, they just messed up.
Even in this case, there is no proof of substantial voter fraud deciding an election. Or even proof of substantial voter fraud. In fact the judge found that King County had poorly managed the process, which is not a matter of in person fraud, which again, isn't a real problem in the US.
