The chart above is from a CBS News / YouGov Poll -- done between April 28th and May 1st of 2,200 respondents nationwide, with a 2.5 point margin of error.
The poll showed Joe Biden with a 6 point lead over Donald Trump. That is consistent with other recent polls.
The poll also questioned about 800 Democrats on who they thought Biden should choose as his vice-presidential running mate. Senator Elizabeth Warren led the pack. About 71% said she should be considered to be the VP choice. Others receiving significant support for consideration were Kamala Harris (59%), Stacey Abrams (50%), and Amy Klobuchar (49%).
When the respondents were asked to pick a single candidate, Warren led the others with 36%. Harris had 19%, Abrams had 14%, and Klobuchar had 13%.
NOTE -- Biden promised during the debates that his VP choice would be a woman.
