A British bookmaker on Friday announced that Sen. Elizabeth Warren (D-Mass.) had overtaken former Vice President Joe Biden as the favorite to win the 2020 Democratic primary.

The bookmaker Ladbrokes said in a tweet that Warren was the 9/4 favorite in their book and was trailed by Biden at 11/4. Sens. Bernie Sanders (I-Vt.) and Kamala Harris (D-Calif.) were tied for third with 6/1 odds and Pete Buttigieg was fifth with 12/1 odds.
