Adding on in this vein: I'm curious if the late Presidential hopeful Ross Perot wrote any noteworthy software, or if his role in tech was only that of a salesman. He's another case of not winning the races for elected office, but 18.9% of the popular vote in 1992 and a fortune of approximately $4 billion in 2019 is nothing to sneeze at.

He was an IBM salesman after the Navy and prior to founding EDS, it's very unlikely he ever wrote any software. I've read a fair bit about him over my lifetime and have never run across a mention of him being technically inclined, an engineer, writing software, etc.

He understood how the IT services industry worked - from his time on the inside of it at IBM - and saw an opportunity. He likely had a good salesman's grasp of the structure of the industry technologically (what was selling, what wasn't; who dominated what segments; what companies were spending on various segments). He got started from spotting a market inefficiency that IBM wasn't interested in pursuing (leasing unused compute time), so Perot formed EDS and the rest is history.
