I don't think what happens in politics is a great proxy for interest. Lots of things with high interest levels never happen - federal digital privacy laws or federal right to repair laws for instance. And, vice versa, lots that are exceptionally unpopular get passed with exceptional rapidity - spying laws and copyright lasting until the heat death of the universe laws are a couple of examples there.
Most polls since the end of the Apollo program have shown strong and growing interest in space. Here's [1] the most recent I could find - a 2018 Pew poll. 72% consider it essential that the US continue to be a world leader in space exploration, 80% agree that the ISS has been a good investment for the country, 63% consider it important (45%) or top priority (18%) to send astronauts to Mars, and so on.
