The Minnesota senator is the third Democrat to drop out of the presidential race since the South Carolina primary on Saturday.
And then there were five.
Klobuchar will appear with Biden at a rally in Dallas on Monday evening, the New York Times reported. She becomes the third candidate in as many days to drop out from the race, following former Mayor Pete Buttigieg of South Bend, Indiana, who dropped out Sunday, and billionaire entrepreneur Tom Steyer, who exited the race on Saturday.
Buttigieg will also endorse Biden, Reuters reported on Monday.
Buttigieg and Klobuchar’s exits come ahead of Super Tuesday, when 14 states and 1,357 delegates are up for grabs, and signals that moderate Democrats are rallying behind Biden, while progressives increasingly consolidate around Sen. Bernie Sanders of Vermont.
Sanders is projected to win the two largest prizes, California and Texas, but it’s uncertain what kind of impact Buttigieg and Klobuchar’s exits will have on the race, particularly after Biden’s nearly 30 point victory in South Carolina.
Sen. Elizabeth Warren of Massachusetts, Michael Bloomberg, the billionaire former mayor of New York City, and Rep. Tulsi Gabbard of Hawaii all remain in the race to become the party’s nominee.
Klobuchar, who mounted something of a long-shot candidacy focused on pragmatism and appealing to moderate voters, received a surge in donations and attention after her surprise third-place finish in New Hampshire, but failed to win even 10% of the vote in Nevada and South Carolina.
She exits the race one day before her home state of Minnesota goes to the polls. Klobuchar was projected to win the state, but her exit could make Sanders the favorite on Tuesday.
