Michael Bloomberg is running at 4 percent nationally as he teases a presidential bid, showing that he’s well known — but widely disliked — by the Democratic electorate, according to a new poll.

No contender is viewed more negatively by Democrats than the billionaire former New York City mayor.

The Morning Consult poll, released Sunday, reflects the enormous challenge confronting Bloomberg as he considers a late entry into the 2020 race. He sits in sixth place, just behind Sen. Kamala Harris of California, and would begin his campaign far outside the top tier.

Nearly 25 percent of likely primary voters view him unfavorably — the highest unfavorable rating in the field — while about 31 percent view him favorably, according to the poll.
