Can’t say I’m surprised by these figures. I’m assuming these figures are based purely on adults living in the US and the two subsets given are (i) Those who vote and (ii) Those who have stated they do not vote perhaps because of apathy or because they are not eligible.
It would be interesting to see what results we would get if we asked a younger group of people, say those who were not able to vote in the last election because they were too young but will be eligible to vote in the next one.
I’d also like to see figures from other countries to see how is performing in an international context.
Living in the UK I’d say he appears to be universally disliked, almost as unpopular as Theresa May our primeminister who is seen as pitiful by many. This view may be skewed by my choice people who surround me as most of them share a similar political outlook to me - though I am hoping not to show any bias here
