Mail Ballot Tracker

Requests and returns are copied from the MCDC "G26 MIB Tracker" sheet maintained by Olivia Quinci, who pulls them from VoteBuilder: county party totals daily, municipality and precinct totals each Friday. This page re-reads that sheet and republishes it with the benchmarks below. If the sheet stops updating, the "as of" line at the top goes stale and a warning appears.

Benchmarks. Mail ballot totals are the county's official per-precinct results (Montgomery County GIS election archive, "Times Cast" mail-in column, split ballot styles summed): 116,958 in the 2022 general and 174,409 in 2024, matching the county's summary reports and, for 2024, OpenElections on every precinct. Two precincts created after 2024 (Upper Dublin 3-3 and 6-3) did not exist in those elections and show no benchmark. Party splits (D / R / unaffiliated) come from the Pennsylvania voter file (vintage ) by the voter's current registration and are shares, not official counts; voters who have since left the rolls are not in them.

Party columns ("D vs 22", "R vs 22", "I vs 22"). A precinct's 2022 Democratic mail benchmark is its official 2022 mail total multiplied by the Democratic share of that precinct's voter-file mail history (same for R and I). "R vs 22" ranks highest-first because a Republican request rate far above the county's is the warning sign to watch, while D and I rank lowest-first because those are the ones to lift. Republican 2022 mail totals were small everywhere, so R percentages run high by construction.

Pace section (state file). The Pennsylvania Department of State publishes one row per mail ballot application for every election since 2020 (data.pa.gov, "General Election Mail Ballot Requests"), extracted from the SURE registration database once a day: county, party, request date, ballot mailed date, ballot returned date, and the voter's congressional, state senate, and state house district, but no precinct. This page reads the Montgomery County rows for 2022 and 2024 (final files) and the 2026 file (live, refreshed with the page) and lines the three up by days before Election Day, so "101% of 2022" means Montgomery County had more applications on the books this many days out than it did at the same point in 2022. Declined applications are excluded. A voter who applied twice (a replacement ballot, a cancelled and reissued one) is two rows, because the file is de-identified. Party here is the party on the application: D, R, "I" for the state's Other/Independent bucket (slightly wider than VoteBuilder's non-affiliated column), and minor parties folded into the total. The state's file and Olivia's VoteBuilder count are counted at different times and by different rules (rows versus people, and VoteBuilder's own filters), so they will never agree exactly; the "Two counts" card shows the gap rather than hiding it.

Districts. Precincts are assigned to the congressional, state senate, and state house district holding the majority of their voters; three precincts (Horsham 4-1, Lower Merion 11-3, Upper Dublin 2-1) are split and shown under their majority district.

Reading the pace column. A request is not a returned ballot. Requests as a share of 2022's final cast count tells you whether a precinct is on track to match its 2022 mail volume; the return rate (once returns begin posting after ballots mail on ~9/18) tells you whether requested ballots are actually coming back. The second number is the one that turns into a canvassing target, and the "Rank by" control switches to it when it becomes available.

"Needed to match county pace" is how many more requests a precinct would need for its requests-to-2022 ratio to equal the countywide ratio. It is a way of sizing the gap, not a quota.

Party columns. "I" is VoteBuilder's non-affiliated bucket; minor parties are included in Total only, so D + I + R runs a few ballots short of Total. Montgomery Township's new precinct lines are not yet reflected in VoteBuilder, so its rows use the old precincts.

All figures are precinct-level aggregates. No individual voter data is published.
