The title of the article is rubbish so I changed it to the truth. If you look at the demographic chart in the article it shows 93% of Hitlery voters give Trump poor marks. Hitlery got 50% of the votes so 93% x 50% = 46.5%
Big surprise that the poll shows 45% say Trump performance was poor. It appears Trump has won over a few of the irrational idiots who voted for Hitlery and kept all the Trump voters, too.
