Oregon was one of the closest states in 2000 and Washington was also targeted, but in 2004, both became much more Democratic, so no I don't think there would be a long term change.
See this is where you guys are so clueless. Bush did better in Oregon in 2004 than he did in 2000.
Let's call it Minnesota syndrome. Trump did worse than Romney in Minnesota. Don't look at the margin, look at the raw numbers.
I was referring to margin, and anyways, both states clearly swung D in 2004 and never looked back, them going D was inevitable.
