Twenty-nine (29) legislative referrals were certified for statewide ballots in 2023 as of Jun. 15. Of that total, six received unanimous support from both parties; six received unanimous support from only Republicans; and 10 received unanimous support from only Democrats, which is higher than 2021 (4) and 2019 (5).

One measure in New York—where legislative constitutional amendments must be considered twice before heading to the ballot—received unanimous support from all members voting of both parties during both considerations of the bill.
