UNDATED -- Democratic Sen. Amy Klobuchar has won a second term.

Klobuchar beat state Rep. Kurt Bills and a third-party candidate in a race that was never seen as close.

Klobuchar's popularity, name recognition and big campaign fund kept big-name Republicans from stepping forward to challenge her.

Bills, a high school economics teacher and first-term state lawmaker, rode support from Ron Paul backers to become his party's nominee. But he had so little money he couldn't mount a major TV presence.

Klobuchar, a former county prosecutor, ran hard anyway. She played up several pieces of legislation she worked on with Republicans as evidence of her bipartisanship.
