How about adding John Wayne? I was told the airport was named after him, not because of his fame and popularity, but because he owned most of the county!

It's my favourite airport ever...
The airport in Washington was renamed by Congress in the late 90s, when there was a Republican majority in both chambers. This was right around when Reagan's deification cult was starting to pick up steam, and there was a nation-wide push to try and get things named after him. Since Congress essentially rules over Washington, this was also not that surprising.
... and even so... I'm positive there are many many more things in the country named after Lincoln, Jefferson, Washington and Roosevelt than there are named after Reagan or either of the Bushes, including the city itself where the 2nd of these airports are located.
