I think there are multiple factors involved. One is caring what the voters think because we are in a position to decide if they win elections. Another is caring what the lobbyists think because money has a major influence on the greedy. Politicians in the U.S. pretty much do a balancing act with those factors and others, and a whole lot of bullshit comes out of their mouths because of it. We also have a lot of dysfunctional laws because of it.
