Warren enters crucial debate with big momentum

Warren enters crucial debate with big momentum-thehill: Sen. Elizabeth Warren (D-MA) is the candidate with the most momentum as the Democratic presidential field heads into a critical debate on Tuesday. Warren has surged in front of former Vice President Joe Biden in recent polls in Iowa and New Hampshire and in some national polls. She also is seeing some encouraging numbers within the polls. Surveys show she has started to appeal to moderate voters and black voters, cultivating a coalition across the party and robbing the Biden campaign of one of its popular talking points.
