Well, I’d grind my own ax some more here :)
The job of Congress is for 530+ individual members to show up and represent concerns of their own voters and build compromise and consensus about what the US government should be doing, whatever concerns those may be.
BUT all too often people are ignoring their own representatives and voting for people who are doing the opposite of what they’d have them do.
Whether voters want their congressperson to be talking about infrastructure or books, well it’s up to them, but they need to make sure their empowered person is doing what they want.
The job of Congress is to represent the concerns of the country, whether those are my concerns or your concerns or not.
