PORTLAND, Maine — Republican U.S. Sen. Susan Collins of Maine won the hardest-fought race of her career, turning back a challenge by Democrat Sara Gideon and winning a narrow majority in the costliest political race in state history.
The outcome, announced on Wednesday, a day after voting ended, gave the 67-year-old incumbent a fifth term in office and dealt another blow to Democrats' hopes for taking control of the GOP-led U.S. Senate.
Speaking as Elton John's "I'm Still Standing" played, Collins thanked Gideon, the 48-year-old speaker of the Maine House, for a "gracious" concession.
"To the people of Maine, thank you. I will serve you with all my heart. I will work hard for you each and every day. And together, we will come together to work on the problems and challenges that are facing our state and our country," Collins told supporters in Bangor.
In Portland, Gideon thanked her supporters in a video address that was transmitted live, but without reporters being present.
"While we came up short, I do believe Mainers in every corner of this state are ready to continue to work together to make a difference," Gideon said Wednesday during the speech.
Republican incumbents proved resilient after tough reelection campaigns, with senators like Collins and South Carolina U.S. Sen. Lindsey Graham triumphing over well-funded challengers. The only two Republican incumbents to go down so far are in Colorado and Arizona.
In Maine, the Senate race was the most expensive political race in state history by far, with Gideon raising nearly $70 million, more than double the $27 million that Collins raised. But that didn't include millions of dollars of so-called dark money. All told, more than $120 million was spent by both candidates and their allies on advertising.
