Session by session
| Session | Roll calls voted on | No votes | In the minority (split votes) |
|---|---|---|---|
| 2025–2026 | 267 of 267 | 73 | 0 of 169 |
| 2023–2024 | 201 of 201 | 22 | 0 of 106 |
How these numbers work
- Counted from the official House and Senate roll calls. Quorum calls are not counted.
- “Roll calls voted on” matches the Missed votes figures below; voting “present” counts as voting.
- A split vote is one where at least one member voted yes and another voted no (ties not counted). “In the minority” means on the side with fewer votes.
- “Whole House” combines every member’s record for the same session. Percentages are shown only with at least 10 votes to count.
- Most bills pass or die without a roll call, so these numbers cover only part of a legislator’s work.
- Party is shown as the Legislature lists it, next to the district. MassVoter never compares, groups or ranks legislators by party.
These numbers describe the record; they are not a grade. A no vote or a minority vote is neither good nor bad. MassVoter never rates legislators.
Committees and leadership · 2025–2026

- Joint Committee on Housing

Most bills are shaped in committee before any floor vote; committee chairs decide which bills move. Source: malegislature.gov (committee lists as of Oct 10, 2026).

How to read this
- Candidates report to OCPF, the state’s campaign finance office. Most file with a bank that reports to OCPF, so totals are updated often.
- “Raised” is all money the campaign took in, including loans from the candidate. “Cash on hand” is what was left on the latest report.
- Shares count contributions only, from the line-by-line reports up to the latest bank report date, so they are shown as percentages. “PACs and other political committees” includes party committees. “Small gifts not listed one by one” are gifts of $50 or less that the law lets campaigns report as one total.
- Outside spending is money spent by groups that are not part of the campaign, such as independent expenditure PACs. The candidate does not control it.
- Federal candidates (U.S. Senate and U.S. House) report to the Federal Election Commission, not OCPF, and are not shown here.
- MassVoter updates these numbers every night from OCPF. Last update: October 12, 2026.
These numbers describe the money; they are not a grade. Raising more or less is neither good nor bad. MassVoter does not connect donations to votes or positions.
Financial interests: State and county elected officials, and candidates for those offices, must file a yearly Statement of Financial Interests with the State Ethics Commission, listing sources of income, business interests and real estate. Anyone can ask for a copy; the Commission tells the filer who asked. How to request a copy (State Ethics Commission)

James C. Arena-DeRosa filed 30 bills as lead sponsor this session. Sorted by subject from each bill’s title; a bill can fall under more than one.
Filing a bill puts an idea before the Legislature. Most bills are not voted on as filed: committees often combine several bills into one new bill, so a law can include a legislator’s idea without carrying their bill number. MassVoter lists what was filed, not what passed.
