With all the controversy with the former President of the U.S., the Democratic Party hired Gallup to collect opinions from voters on whether or not they believed President Trump was an honest person. They asked participants, "On a scale from 1 to 10 (1 being the lowest, 10 being the highest), how honest is President Trump?" They were interested in finding out the response in comparison to the relationship of party affilation (Republican or Democrat). Gallup interviewed by telephone over 2000 people in the U.S. who had indicated that they were registered voters.
