Very possibly someone else somewhere has made note of it, but we can't recall seeing it anywhere, and merits some mention here regardless:
Turns out that the percentage of the vote Democrat Barack Obama received this month in Washington (57.6%) and in Oregon (56.8%) was the highest any presidential candidate has received since Lyndon Johnson (whose numbers were 62% in Washington and 63.7% in Oregon) in 1964. Higher than Clinton, Reagan, Nixon/72. He was the most popular presidential candidate in those states in the last 44 years. Duly noted.
