Harris surges, Biden slips after debate: new poll

Senator Kamala Harris has received a surge in support among Democrats following last week's US presidential candidate debate while former vice president Joe Biden has slipped, according to a poll published Tuesday. Twenty percent of Democrats surveyed in the Quinnipiac University poll said they backed Harris, the junior senator from California, up from just seven percent in a June 11 Quinnipiac poll. Biden, who served as vice president under Barack Obama and has been seen as the frontrunner in the race, saw his support drop to 22 percent in the new Quinnipiac poll from 30 percent in the June 11 survey.
