The charts above are from the weekly Morning Consult Poll. The poll was done between June 17th and 23rd of a national sample of 16,188 registered voters who say they will vote in the Democratic primary. The margin of error is 1 point.
The charts show the leading candidates -- the top one is national and the bottom one is in the four earliest primary states.
The Democrats will hold their first debates tonight and tomorrow night. It will be interesting to see if the debates change anything.
