The Times/Siena poll of 3,766 registered voters was conducted from Oct. 13 to Oct. 26. The margin of sampling error for an individual state poll is plus or minus 4.4, except for Michigan at plus or minus 5.1 points. Together, the battleground sample has a margin of error of plus or minus 1.8 percentage points.
Also, I found this to be interesting:
The Biden voters who say Ms. Warren is too far to the left are relatively well educated and disproportionately reside in precincts that flipped from Mitt Romney in 2012 to Mrs. Clinton four years later. They oppose single-payer health care or free college, and they support the Republicans’ 2017 tax law. They are not natural Democratic voters: 41 percent consider themselves conservative; 20 percent say they’re Republican; 33 percent supported Mr. Trump or Mr. Johnson in 2016.
