These charts reflect the results of the new Quinnipiac University Poll -- done between June 6th and 10th of a national sample of 1,214 voters, with a margin of error of 3.5 points.
The poll shows Trump is in a lot of trouble. Right now, Joe Biden would beat him nationwide by 13 points. And Biden's not the only one that could beat Trump. Sanders would beat him by 9 points, Warren by 7 points, Harris by 8 points, Buttigieg by 5 points, and Booker by 5 points.
The poll also queried 503 Democrats and leaners about who they would support in the primary. Those results are in the chart below. Currently, Biden, Sanders, and Warren are the only candidates in double figures.
