SurveyUSA notes:

Al Gore won Oregon in 2000 by 6,765 votes. With that one asterisk noted, Oregon has been reliably “blue” since 1988, when it was one of the nine states that voted for Michael Dukakis. Before 1988, however, Oregon was reliably red, voting for Republicans in every election from 1948 through 1984, with the sole exception of 1964.

The poll, which has a 4.3% margin of error was released on Feb 22.
