Only three candidates were on the ballot for the Oregon U.S. Senate race, nominees of the Democratic, Republican, and Constitution Party. It appears likely that the Constitution Party tipped the outcome in this race. Although the votes counted (as of 2:30 pm Pacific time) show Gordon Smith (Republican) leading, the vast bulk of uncounted votes are from Multnomah County, which includes Portland and is very Democratic-leaning. The results now are Smith 663,126; Jeff Merkley (Dem.) 658,409; David Brownlow (Constitution) 75,968. Over 190,000 votes remain to be counted from Multnomah County.

The CP did much better nationally than in previous years, considering they weren’t on the ballot in CA, TX and NY. Baldwin actually outpolled Barr in a few states.
I guess we can estimate then that Brownlow got something like 6% of the vote.
