On the other side of that commemorative coin, Sanders was thought to have had the best coverage at 39%, Bloomberg next at 24%, Buttigieg (13%), and Biden (8%). 

That is not a big surprise given that after Biden's poor showings early on, many were leaving his campaign for dead while crowning Sanders the presumptive nominee if he remained on the same trajectory, as appeared likely at the time.

The survey was of 10,300 U.S. adults. The margin of error is plus or minus 1.5 percentage points.
