Chasey earned her PhD in special education from University of New Mexico and her JD from the University of New Mexico School of Law.
In 2019, Chasey introduced legislation that would prohibit disenfranchisement of felons. If the bill is successful, New Mexico would become the third state (in addition to Maine and Vermont) to allow felons to vote while serving sentences.
Chasey became Majority Leader of the New Mexico House of Representatives in 2023. She did not run for re-election in 2024, and she was replaced by fellow Democrat Marianna Anaya.
