Between 2010 and 2022 in states with a two-session requirement, what percent of constitutional amendments that made it through the first session before a change in party control of the legislature ended up failing in the second session?

You answered: 93%.
The correct answer was 79%.

Between the 2010 and 2022 legislative sessions, 106 constitutional amendments were approved during one legislative session in the states with two-session vote requirements. However, 40 of these constitutional amendments (37.7%) failed during the second legislative session.

From 2010 to 2022, when there was a change in party control of the legislature between legislative sessions, 79% (11 of 14) of the constitutional amendments approved during the first session failed and 21% (3 of 14) passed during the second session.

• Example: In 2015, the Republican-controlled Nevada State Legislature approved five constitutional amendments for the first time. Democrats controlled the legislature during the next legislative session in 2017, and four of the five constitutional amendments did not receive a floor vote.

• Example: In 2009 and 2010, Democrats controlled the Wisconsin State Legislature and approved three constitutional amendments. Republicans controlled the legislature during the next legislative session in 2011, and zero of the constitutional amendments received a floor vote.

The following is a list of constitutional amendments in which two different political parties controlled the legislature during successive sessions:
