The chart above reflects the results of an NPR / PBS NewsHour / Marist Poll -- done on March 13th and 14th of a national sample of 784 registered voters, with a 4.89 point margin of error.
It shows that the voting public does not believe the Coronavirus information being given to them by Donald Trump. They heard him call it a hoax and just the flu, and combined with his thousands of other lies, they no longer believe him. They know he is just trying to make himself look good, and only provides the info that does that.
The public wants the truth (however bad it may be), and they know they won't get it from Trump.
