FILE - Election 2020 Pete Buttigieg

Democratic presidential candidate South Bend, Ind., Mayor Pete Buttigieg.

Former Vice President Joe Biden and Massachusetts Sen. Elizabeth Warren have company near the top of the latest Iowa poll.

A Suffolk University and USA Today telephone poll shows that while Biden is the front runner with 18 percent support and Warren close behind at 17 percent, South Bend, Indiana, Mayor Pete Buttigieg occupied third place with 13 percent support.

Buttigieg, 37, switched spots with Vermont Sen. Bernie Sanders, whose nine percent support has him in fourth place. Billionaire Tom Steyer rounded out the top five with California Sen. Kamala Harris, Minnesota Sen. Amy Klobuchar, and Hawaii Rep. Tulsi Gabbard locked in a three-way tie in sixth place.

The polling has a 4.4 percentage point margin of error, with 500 likely Democratic caucus-goers surveyed.

While the poll is a positive for Buttigieg, he still has an uphill battle to catch Biden, with greater name recognition and a front-runner from the beginning, and Warren, whose war chest has nearly $26 million in cash on hand.

Sanders, who was recently hospitalized after suffering a heart attack, returned to the campaign trail and earned an endorsement from two-fourths of The Squad. Congresswomen Alexandria Ocasio-Cortez and Ilhan Omar have announced that Sanders, who has close to $34 million cash on hand, has their support.

According to RealClearPolitics’ national polling average, Buttigieg has made some progress nationally as well, garnering 5.8 percent support to fall behind Biden, Warren and Sanders.
