Willette will likely face a crowded field vying to replace Michaud. Already, Maine businessman Blaine Richardson has said he also plans to seek the Republican nomination.

Former state House Minority Leader Emily Cain — who herself was first elected to the state legislature at the age of 24 — said she will compete for the Democratic nomination. She could face Secretary of State Matt Dunlap or Attorney General Janet Mills in her push for the Democratic nomination.

If Willette were elected, he actually would not be the youngest member of the U.S. House. Former one-term Rep. Jed Johnson (R-Okla.) was only 24 when he was elected in 1964, but turned 25 shortly before being sworn in. Rep. Patrick Murphy (D-Fla.), 30, is currently the youngest member of Congress.
