How each side wins

From the forecast, the polls, the county map, voter groups, money and ballots
If you work for Jeff Merkley
  1. Protect the lead

    Jeff Merkley leads by 24.4 in the forecast and wins 100% of simulations. The cushion is about 501,044 votes; a one point swing is about 10,276 voters changing sides.

  2. The range

    In 8 of 10 simulations the result lands between D +15.8 and D +32.8. Only an unusual polling error changes the winner.

  3. Turn out the base

    The biggest vote banks for Democrats: Multnomah, a projected net 282,582 votes; Washington, a projected net 125,217 votes; Lane, a projected net 65,038 votes. Every point of extra turnout here is worth more than persuasion anywhere else.

  4. Win the battlegrounds

    The large counties within 12 points: Marion, D +7.1, 6.9% of the vote; Jackson, D +4.0, 5.4% of the vote; Yamhill, D +1.9, 2.5% of the vote; Polk, D +3.4, 2.1% of the vote.

  7. Where you lose ground

    The forecast's worst groups for Jeff Merkley: Immigration voters 20 to 77, Small counties 44 to 52, Midsize counties 47 to 49. Cutting the loss here is often cheaper than winning new groups.
