Biden heads the 2020 Democratic field, but his lead is shrinking

Former Vice President Joe Biden is the presumptive front-runner of the Democratic 2020 primary field, even though he has yet to declare he’s running for the Democratic nomination.

Biden has a more than 10-percentage-point edge on his closest rival, Sen. Bernie Sanders, according to the latest polling averages compiled by RealClearPolitics. Biden, who told reporters last weekend he would announce his 2020 intentions “in the near term,” draws on average 27.5 percent of the vote in comparison to Sanders, who attracts almost 17 percent. Biden’s 10-point lead, however, is shrinking — a handful of earlier polls gave him a 20-point margin over the independent senator from Vermont.
