The Democratic presidential contest now has two frontrunners, not just one. Who is ahead depends on which question you ask in the latest Economist/YouGov Poll. Former Vice President Joe Biden and Massachusetts Senator Elizabeth Warren are at the top of the two dozen active candidates.

Warren is more popular than Biden: 75 percent of Democratic primary voters have a favorable opinion of her, five times the percentage who are unfavorable. On this item, Biden’s favorability rating is lower – and not much higher than that of Vermont Senator Bernie Sanders, California Senator Kamala Harris, former Texas Representative Beto O’Rourke, and South Bend Mayor Pete Buttigieg. New Jersey Senator Cory Booker is also close to the leaders.
