Sen. Michael Bennet has narrowly defeated tea party Republican Ken Buck to win a hard-fought Senate seat in Colorado.
The victory for Bennet allows Democrats to hold onto a seat once viewed a prime opportunity for the Republicans to make gains.
Bennet provided a crucial firewall against further Republican gains in the Senate during midterm elections. The race attracted more out-of-state campaign money than any other Senate contest this year.
In a victory speech, Bennet called it a "race for the record books."
