Sen. Collins: 'I will serve you with all my heart'

"I am the first person since Maine directly elected its senators to win a fifth term," Collins said.

Collins, 67, turned back one of the strongest challenges in her career as she defeated Democrat Susan Gideon, 48, the speaker of the Maine State House of Representatives.

Gideon said she called Collins to concede the race.

The result is a setback for Democrats, who hope to pick up at least three seats to win control of the 100-seat Senate. Collins had been viewed as one of the more vulnerable Republicans.
