It’s a “dem state” because of Multnomah County and nothing else. 90% of the land area where people also live is conservative. Same way in Washington State, where the liberals control King County and Seattle. Get away from the Seattle area and rest of the state is reliably republican, especially east of the Cascades. It’s a shame that one little area of a state can determine the politics for the rest of the state.
Sort of like Florida, California and New York controlling the government. Which is a prime reason the we do not want a direct election of he President.
