National poll: Biden 52, Sanders 36

Massachusetts Sen. Elizabeth Warren, who dropped out of the race on Thursday, lands at 7% in the poll. That is largely due to her 18% showing in interviews conducted on Wednesday, before she ended her campaign. Among those interviewed after she left the contest, Biden’s support rose to 57%, Sanders stood at 36%, while 2% volunteered that they still backed Warren. Another 6% chose someone else or were unsure about who they would support.

Biden’s successful Super Tuesday appears to have led to a rebound in his favorability rating (48% overall now hold a positive view, up from 39% in December), while Sanders has hit his highest unfavorability rating yet in CNN polling back to 2015 (52% hold an unfavorable view of him, up from 44% in December).
