After traling their announcement all weekend. the New York Times editorial board announced that it could not decide between two choices for democratic presidential nominee, one one the left, the other a centrist.

Senators Elizabeth Warren of Massachusetts and Amy Klobuchar of Minnesota got the endorsement, which was declared Sunday on an episode of The Weekly podcast. A 3,452-word rumination by the editorial board concluded: "May the best woman win."

The board wrote: "Amy Klobuchar has emerged as a standard-bearer for the Democratic center. Her vision goes beyond the incremental. Given the polarization in Washington and beyond, the best chance to enact many progressive plans could be under a Klobuchar administration."

The two candidates take different approaches to their candidacies, with Klobuchar, 59, offering a pragmatic approach and Warren, 70, pitching a left-wing vision of dramatic structural change.

"Three years into the Trump administration, we see little advantage to exchanging one over-promising, divisive figure in Washington for another. Good news, then, that Elizabeth Warren has emerged as a standard-bearer for the Democratic left," the board said.

“May the best woman win," the editorial board said.

The editorial board had narrowed down its choices to four candidates: Warren and Klobuchar, former South Bend, Indiana, Mayor Pete Buttigieg, and New Jersey Sen. Cory Booker, who dropped out of the race after his interview with the editorial board.

In his interview with the editorial board, former Vice President Joe Biden, 77, pushed back against concerns that he was too old to be president and defended his foreign policy record, noting that he had disagreements with President Barack Obama on Afghanistan policy. Members of the editorial board expressed concern that he was not inspiring enough, among other concerns.

It is unclear how much endorsements from newspapers and prominent public figures helps a candidate. The New York Times has a hit-or-miss record with endorsing candidates.

In 2016, it endorsed former Secretary of State Hillary Clinton for the Democratic presidential nomination, calling her "one of the most broadly and deeply qualified presidential candidates in modern history." Ohio Gov. John Kasich got its endorsement for the Republican nomination, calling eventual nominee Donald Trump and Texas Sen. Ted Cruz "equally objectionable for different reasons."

It also endorsed Clinton in the 2008 Democratic primary race rather than Obama after early state nominating contests had started, and Obama had won Iowa and Clinton finished first in New Hampshire.

"The next president needs to start immediately on challenges that will require concrete solutions, resolve, and the ability to make government work. Mrs. Clinton is more qualified, right now, to be president," it said.

In 2004, the paper endorsed eventual nominee John Kerry, also after the then-Massachusetts senator and future secretary of state had won state contests in Iowa, New Hampshire, and elsewhere.

In general election races, the New York Times has endorsed the Democratic nominee in every election since 1960.

The Des Moines Register, a newspaper prominent in Iowa politics, has not yet revealed its primary endorsement. The Quad-City Times, a regional paper in Eastern Iowa, endorsed Klobuchar on Saturday.
