Joe Biden is looking to put Bernie Sanders away on Tuesday, when the two face off in four primary races, with polls showing the former vice president riding double-digit leads.

The Vermont senator had positioned himself as the leading Democratic contender for much of February after a strong showing in Iowa and victories in New Hampshire and Nevada.

But Biden, buoyed by endorsements from former rivals in the Democratic presidential primary race, bounced back, taking 10 of 14 states on Super Tuesday, then four out of six contests last Tuesday.

He is now poised to build on his roughly 150-delegate lead over Sanders on his way to the 1,991 total needed to be nominated at this summer’s Democratic National Convention.

Florida, Illinois, Ohio and Arizona are all planning to hold primaries on Tuesday.

Biden has a 38 percentage-point advantage over Sanders in Florida — at 65 percent to 27 percent — according to a Gravis Marketing survey released last Friday.

Sanders’ numbers in the Sunshine State suffered after he made comments last month on “60 Minutes” praising some of the late Cuban dictator Fidel Castro’s policies.

Biden also leads Sanders in Illinois by 21 percentage points, according to an Emerson poll; by 22 points in Ohio, according to an Emerson survey; and by 17 points in Arizona, according to a Univision/ASU poll.

Speaking hours before the presidential debate Sunday night, former Democratic National Committee Chair Ed Rendell predicted that barring any catastrophe on that stage, Biden would bag the nomination with primary wins on Tuesday.

“It looks like the nomination will be virtually clinched after next Tuesday,” Rendell told host John Catsimatidis on his AM 970 show, “The Cats Roundtable.”

“Unless something dramatic happens in that debate Sunday night . . . the race for the nomination would be effectively over next Tuesday night, regardless of whether Sanders suspends his campaign or keeps it going until the convention.”

The former vice president and the democratic socialist are going face-to-face for the first time since almost all the other Democratic presidential candidates dropped out of the race.

Unlike Georgia and Louisiana, which delayed their primaries over concerns about the coronavirus, the four states going to the polls on Tuesday are encouraging people to vote or mail in their ballots early, under advice from the Centers for Disease Control and Prevention.

Those unable to do so have been advised by election officials to try to avoid standing in lines to reduce the risk of infection.
