Warren sits within margin of error behind Biden in lastest national Democratic primary poll - The Boston Globe
The race for the Democratic presidential nomination is both competitive and fluid less than 100 days before the Iowa caucuses, with a stable trio of leading candidates and a fourth — Pete Buttigieg, the mayor of South Bend, Ind. — now rising above a dozen others in the low single-digits, according to a Washington Post-ABC News poll.
Democrats see former vice president Joe Biden as the strongest leader among the top candidates and also say he has the best chance of defeating President Trump.
