Morning Consult’s latest 2020 tracking data measured an increase of 4 percentage points from the previous week in the share of voters who picked him as their first choice for the party’s presidential nomination. It gives the former vice president a 10-point bump in the two polls conducted since he launched his bid for the presidency last month, an upward swing unmatched by any other candidate in the race.
Four in 10 Democratic primary voters ranked Biden as their first choice in the primary, up from 36 percent in the prior week, cementing his early status as the front-runner amid attacks on his progressive bona fides from Sen. Bernie Sanders (I-Vt.).

Sanders – who’s polling second with 19 percent – is down 5 points since Biden’s April 25 announcement, while South Bend, Ind., Mayor Pete Buttigieg is down 3 points over the same time period.
