Monmouth National: Biden 33, Sanders 15, Harris 11, Warren 10

One of the more fascinating things about Harris is that amongst Democrats, she consistently polls very low when it comes to unfavorability. It's lower than the unfavorable ratings of Yang, Klobuchar, Buttigieg, Castro, Delaney and even those of Williamson, Gravel, Bullock, and Ryan, and unlike every other candidate, it's actually DECLINED overtime. Her rating was 4 points higher back in January than it is now.

Favorable/Unfavorable:

Biden: 74%/17%
Sanders: 65%/21%
Warren: 60%/14%
O'Rourke: 40%/19%
Harris: 58%/9%
Klobuchar: 32%/10%
Buttigieg: 35%/11%
Booker: 41%/13%
Gillibrand: 28%/17%
Castro: 28%/10%
Delaney:13%/12%
Yang: 12%/13%
Williamson: 10%/10%
Gravel: 5%/10%
Ryan: 15%/15%
Bullock: 11%/11%

I'm shocked that 11% of democrats have an unfavourable view of Buttigieg. The guy is IMO the most easily likable candidate for a major party I have witnessed in my lifetime.

Some of those people presumably don't know who he is, but are just saying they have an unfavorable opinion anyway.  (And the same goes for everyone else in this poll, though less so for those with the highest name recognition.)  I remember years ago PPP did an experiment in which they polled the favorability of a fake name, and the numbers were similar to what Gravel has in this poll: ~15% or so claimed to have an opinion of them, and the opinion skewed negative, even though it wasn't a real person.  Presumably that's because there are people who don't want to admit that they don't recognize a name in a poll, and are more comfortable offering a negative opinion of an unknown person than a positive opinion.  Or maybe they just instinctively offer a negative opinion of everyone except their one or two favorites.

That could be it.
