HIGH POINT — Former Vice President Joe Biden and U.S. Sens. Bernie Sanders and Elizabeth Warren are the top three picks at this point of potential Democratic primary voters.

A High Point University Poll published Monday found that 31 percent of self-identified Democrats would support Biden if a primary election were held today. Twenty percent would vote for Sanders, and 15 percent would back Warren.

Nine percent of Democrats are undecided, which polled higher than Sen. Kamala Harris (6 percent), Sen. Cory Booker (4 percent) and the rest of the crowded field.

Biden also had the highest favorability rating among Democrats, according to the HPU Poll, with a 70 percent score. Sanders (61 percent favorable), Warren (53 percent) and Harris (46 percent) trailed.

But Democrats appear to be still making up their minds about who they might support. Only 41 percent said they had given "a lot" of thought to the Democratic candidates while 36 percent said they had paid "some" attention to the race.
