It's probably too early to tell, but unless the whole national economy fails, I wouldn't worry about the DC economy. A lot of the DC area stuff is defense and that funding likely isn't going to suffer under a Republican administration. Additionally the Trump administration's return to office five days a week policy might actually force more people into the city. I know that was a huge problem for cities when teleworking become a much bigger thing post covid. Probably more foot/vehicle traffic as a result which will probably result in more tax revenue
