Graham Platner (D) defeated David Costello (D) to win the Democratic primary for U.S. Senate in Maine on June 9. Platner will face incumbent Susan Collins (R) in the general election on Nov. 3.
Ahead of the primary, the New York Times wrote, "To have any chance of retaking the Senate, Democrats must defeat Ms. Collins, a Republican who is widely seen as vulnerable but who has repeatedly dashed their hopes of unseating her."
Governor Janet T. Mills (D) initially ran but suspended her campaign on April 30, saying, "While I have the drive and passion, commitment and experience, and above all else — the fight — to continue on, I very simply do not have the one thing that political campaigns unfortunately require today: the financial resources." Before suspending her campaign, Mills received endorsements from U.S. Sens. Chuck Schumer (D-N.Y.) and Catherine Cortez Masto (D-Nev.) and polled second behind Platner.
