SARA BURNETT Associated Press Minnesota Sen. Amy Klobuchar ended her Democratic presidential campaign on Monday and plans to endorse rival Joe Biden in an effort to unify moderate voters behind the former vice president's White House bid. She is flying to Dallas and plans to join Biden at his rally Monday night, according to her campaign. Klobuchar was the third presidential candidate to drop out of the race in less than 49 hours, following Pete Buttigieg's departure late Sunday and Tom Steyer's exit late Saturday. Their decisions reflect an urgent push among moderates to consolidate behind Biden as a counter to progressive rival Bernie Sanders. Klobuchar outlasted several better-known and better-funded Democrats, thanks to a better-than-expected third-place finish in New Hampshire.
