I specifically mentioned favourability (I got my numbers from the RCP averages of Nov 8 and the day I posted) because unlike job performance you can track it from before the election - and he has gained substantially. And his GOP numbers in 2 of the polls I saw in detail were sky-high.
Nov's result was the 1st time such an unfavoured candidate won, but, if you had seen HRC's numbers in isolation you'd always expect her to be the lsing candidate. It was an exceptional race.
The issue-based polls you have posted are interesting since the ones posted in the thread painted a different picture (the Morning Consult-Politico that you haven't included), and I didn't go looking for more. But bear in mind that opposition intensity is brilliant right now, combined with a judicial attack too.
His best polling comes from economy/ability to get things done. Interviews with his supporters suggest that he is expected to deliver as a CEO more than a president.
I know a group of liberals and leftists in India who convinced themselves that India's centuries of secularism or some such platitude would see us reject Modi - he won the biggest majority in 30 years. Anyone with a pulse could tell how wrong they were, for at least 2 years before the election. I
HATE that complacency, so maybe I'm going too far the other way, but I don't see these Trump numbers as catastrophic - especially given that by most objective standards he's had an absolutely purely disastrous start.
@langster
I followed the tweet you posted about losing support but it didn't lead to any poll showing that.
