Gallup has published Donald Trump's approval rating in each of the 50 states. This is based on over 170,000 interviews conducted during 2017. Trump's national approval rating averaged 38% during 2017, with 56% disapproving. Breaking it down by state, the results ranged from 26% in Vermont to 61% in West Virginia. (Washington D.C. gave Trump an approval rating of 6%).
Gallup found that Trump had approval ratings above his 38% national average in 33 of the 50 states. This occurred because some of the states where he performs most poorly are very populous states like California. At a high level, this outcome sounds pretty similar to what we saw in the 2016 election, where Trump surpassed 270 electoral votes while losing the popular vote.
Texas appears to be the biggest surprise; Trump's approval here was just 39%. A couple caveats to keep in mind: the surveys were taken over the course of an entire year, so not really a snapshot in time. Also, the surveys were of adults; no consideration given to voter registration status. That last point might help explain the low number in Texas, as Latinos have historically voted at lower rates than whites.
The above in mind, it probably isn't totally fair to try and translate approval ratings into a 2020 electoral map. Of course, if one published a website around electoral maps, they might do it anyway. So here it is. The map is interactive, so if you don't agree with our categorizations (below the map), you can change them and create your own.
