How each side wins

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

    Ed Markey leads by 33.3 in the forecast and wins 100% of simulations. The cushion is about 952,148 votes; a one point swing is about 14,297 voters changing sides.

  2. The range

    In 8 of 10 simulations the result lands between D +26.3 and D +40.1. Only an unusual polling error changes the winner.

  3. The polls

    The polls page average is D +24.5. Your best recent poll is Suffolk University/Boston Globe at D +26.6; your worst is University of New Hampshire at D +23.2. 4 polls in the last 30 days.

  4. Turn out the base

    The biggest vote banks for Democrats: Middlesex, a projected net 324,676 votes; Suffolk, a projected net 177,703 votes; Norfolk, a projected net 105,859 votes. Every point of extra turnout here is worth more than persuasion anywhere else.

  5. Win the battlegrounds

    The large counties within 12 points: Bristol, D +10.6, 7.7% of the vote.

  6. Where you run behind the 2024 map

    Against the 2024 presidential vote, Ed Markey runs furthest behind in Barnstable, Norfolk, Worcester. That is where the forecast sees voters who backed your side two years ago and have not come back yet.

  7. The coalition levers

    Groups big enough to move the race: White voters, 77% of voters, 60 to 37, where a 5 point gain is worth 3.85 points; Men, 46% of voters, 60 to 37, where a 5 point gain is worth 2.29 points; Voters who can afford daily costs, 38% of voters, 56 to 36, where a 5 point gain is worth 1.90 points.

  8. Where you lose ground

    The forecast's worst groups for Ed Markey: Immigration voters 34 to 59, Voters who can afford daily costs 56 to 36, 2024 voters who skipped 2022 56 to 36. Cutting the loss here is often cheaper than winning new groups.

  9. The money

    $1.3M cash against $712K. Spend it early on persuasion television in the battleground counties and keep a reserve for the last week.

  10. What the ballots so far say

    The early vote has moved this forecast 0.3 points toward Ed Markey. Bank it: chase the remaining mail ballots and low propensity voters who have not voted.

  11. John Deaton's strongest asset

    Air cover: Outside groups spent $205K helping John Deaton and $43K helping Ed Markey.
