This happened to Jack Schmitt in ArizonaNew Mexico, as well. His opponent's campaign slogan was "What *On Earth* Has Jack Schmitt Done For Us?" https://t.co/FUr9endlmH
I would note that this is another problem with a government space program in a representative republic, and why it’s hopeless to think we can do Apollo again. People who want to see space science happen need to look to other funding sources.
Breakthrough and NASA have signed a Space Act Agreement for support of a private mission. This is the most likely way for it to happen, and it will probably happen before a Europa mission (it probably would have even with Culberson, given the requirement to use SLS).
