Over a 2022 replay, 0.6% of the statewide gap
In 2022 Shapiro lost Somerset by 13,086 votes. At the target, on about 31,671 ballots at 2022 turnout on today's roll, Garrity would carry the county by 17,273 votes. That is 4,551 net votes better for her than a 2022 replay on the same roll.
How turnout is measured
Turnout is votes in the top race divided by registered voters. The top race is governor in 2014, 2018 and 2022 and president in 2016, 2020 and 2024. The state's returns files have no total-ballots count, so this undercounts by the roughly 1% who skip the top race.
The state's own 2024 count of people who voted in Somerset is 41,099, against 40,881 presidential votes.
A turnout rate can rise because the roll shrank, not because more people voted. That did not happen to a large degree here: no four-year span saw the roll fall 5% or more while votes held within 3%. Warren is the clearest case statewide: 20,650 presidential votes in 2020 and 20,723 in 2024 on a roll that fell from 31,431 to 26,871.
