Former Vice President Joe Biden is beginning to pull away as the frontrunner in the 2020 Democratic presidential primary election as he picked up key victories to extend his delegate lead over Sen. Bernie Sanders, I-Vt., in the March 10 primaries.
As of Thursday morning, the 77-year-old Biden holds a 864 to 710 lead over Sanders. On Tuesday, Biden picked up wins in four states, including the biggest prize, Michigan.
Along with Sanders and Hawaii Rep. Tulsi Gabbard, Biden is one of just three candidates left vying for the party’s nomination.
