WASHINGTON — Cory Booker is trying to get the numbers to add up to 2020.

The U.S. senator from New Jersey will be one of 12 Democratic candidates on the stage Tuesday for the fourth presidential debate in Ohio (and has qualified for the fifth one to be held Nov. 20 in Georgia).

He’s done well in the first three debates, is expanding his field operations in the early caucus and primary states, and continues to land key endorsements.

But he shows little movement in opinion polls, and it’s getting late. The odds of him winning are long. And he lags in fundraising, even after hitting his targets.

Here’s how Booker compares with the other candidates he will debate Tuesday night.

A second-tier candidate

The Washington Post’s latest ranking of the Democrats most likely to be nominated dropped Booker one place to sixth, flipping him with Pete Buttigieg, mayor of South Bend, Indiana. Booker and Buttigieg were grouped in the second tier of candidates with U.S. Sen. Kamala Harris of California.

The Post’s top tier consisted of the three consistently polling in double figures, former Vice President Joe Biden and U.S. Sens. Elizabeth Warren of Massachusetts and Bernie Sanders of Vermont.

U.S. Sen. Amy Klobuchar of Minnesota, former Rep. Beto O’Rourke of Texas and former Housing and Urban Development Secretary Julián Castro comprised the third tier, and entrepreneur Andrew Yang and investor Tom Steyer and Rep. Tulsi Gabbard of Hawaii made up the fourth tier.

Here are the 12 who will be on stage, and here’s how the Post ranked them all, with previous rankings in parentheses:

1. Elizabeth Warren (1)

2. Joe Biden (3)

3. Bernie Sanders (2)

4. Kamala Harris (4)
