You look at approval ratings accross the globe and most all leaders are very very bad. Quite a few even big names are lower than Trump. I'm more inclined to believe that most all people just hate their leaders/govt in general versus it being a sole trump thing.
But as above person said, polls aren't the most reliable things these days.
I'd be very interested in reading your source on that. And the link I shared has past presidents as a comparison point, so of course your apologetics is lacking.
National polls were within 2 points, state polls within 3.7. Have your 3.7, hell have your 5-6 points (like WI polls) and you're still left with a resoundingly abysmal approval rating.
But hey, don't allow facts to tread on your fantasy.
