On Day 984 Obama dropped to 42.8% approval. That is where Trump is now. Trump isnt higher they are the same. Now, even that seems troubling until you realize that is almost all on Obama taking a dip after he peaked at over 52% 4 months earlier. 3 months after that he was back over 48% and still climbing. (he would hit 53% in the next year)
Meanwhile Trump has been hovering between 39-42% since a year into his presidency. In fact, 42.8% is one of the 3 the HIGHEST approval rating he has had since March 14th, 2017 when he was at 44.8%. This is not the mark of some great upward trend or anything...look at the trend line it is always the same. (looks like the brainwaves of a man in a coma...ironic)
So while yes technically this is the first time the numbers are the same, in truth that is cause Obama's numbers crashed for a bit. The truly important factor isnt that Trump equaled Obama it is that it took one of Trump's best polling days (top 2-3 after the inauguration bubble deflated) to reach the levels of approval on Obama's worst polling day. That is how disapproved of Trump is. This is like when the Gophers beat Alabama in a bowl game years ago. Sure Alabama was a shell of what it had been (and would soon return to) and was coming off probation and playing in a mediocre bowl but you can bet the locals loved saying it cause it sounded good. If you actually analyze it though it was not a very impressive feat.
