In a wealthy 2020 Democratic presidential field, Pete Buttigieg lags behind the pack.
The South Bend, Indiana, mayor makes a comfortable living. He and his husband, Chasten, earned $152,643 last year, according to tax returns.
Even so, Buttigieg made the least in 2018 out of the 13 Democratic presidential candidates who have released their tax returns. Former Vice President Joe Biden and his wife, Jill, led the field by raking in $4.5 million, according to tax returns. Sen. Kamala Harris of California and her husband, Douglas Emhoff, followed with $1.9 million.
