Nate Silver: 47% strongly disapprove of Trump, only 20% strongly approve

Trumps problem is that there arent many voters who could plausibly be persuaded to join the Trump train, at least not on short notice. Not only are Trumps disapproval ratings high about 58 percent of the country now disapproves of Trumps job performance, the highest figure of his presidency to date but also most of the voters who disapprove of him do so strongly.
In May, when we looked at polls that broke Trumps approval rating into four categories strongly approve, somewhat approve, somewhat disapprove and strongly disapprove we found that his strong disapproval ratings exceeded his strong approval ratings by about a 2:1 margin. The numbers have actually gotten a little worse for Trump since then. His strong disapproval rating, based on the technique FiveThirtyEight uses to calculate approval ratings, is now 47.4 percent, up from 44.1 percent on May 23. And Trumps strong approval rating is just 20.4 percent, down a tick from 21.4 percent in May.
As we wrote back in the spring, its something of a myth that Trump has an enormous base thats impervious to any and all missteps from the White House. Instead, he has his fair share of support, but its a mix of base voters (about 20 percent of the population) and other voters who support him more reluctantly (16 or 17 percent of Americans somewhat approve of Trump).
What Trump doesnt have is very many people who somewhat disapprove of his performance; this group makes up only about 11 percent of the country. It might not sound helpful to have voters who somewhat disapprove of you, but theyre a lot easier to bring over to your side than voters who strongly disapprove of you.
