A new Hamster 2020 poll shows a tightening race for the Democratic nomination for president, with a 67-way tie for 18th place.

Joe Biden, Bernie Sanders, Elizabeth Warren and Kamala Harris led the poll by a wide gap, with Pete Buttigieg and Andrew Yang leading the second tier. The candidates are bunched together after that, though, with 67 of them tied for 18th place with 2 percent of the vote.

Hamster analysis shows that these candidates will need to differentiate themselves from the rest of the field of 148 if they are to break into the top 17. Beto O’Rourke finished 19th, with 0.3 percent.
