A new poll shows businessman Rick Caruso has significantly cut into Democratic Congresswoman Karen Bass' lead in the race to be the next mayor of Los Angeles.

According to the poll, conducted by the UC Berkeley Institute of Governmental Studies, Bass leads Caruso by just three percentage points among registered voters in the city, 34% to 31%, down from a double-digit lead she held over the Republican-turned-Democrat back in the summer.

Among likely voters, however, Bass still holds a significant advantage over Caruso, leading with 46% to his 31% with just a little over five weeks ahead of Election Day. That margin, however, has also been reduced from a more than 20-point lead just last month.

Caruso's greatest advantage is with Asian voters, who favor him over Bass 51% to 29%, with 20% still undecided.

Every other racial demographic favors Bass, while Caruso is favored by both Republicans and those not aligned with a particular political party.
