That's sort of a progressive bias in looking at things. That governance should actively be doing something, enacting some policy. But voters aren't necessarily voting to enact policies. They could be voting because they sort of have to in order to keep people who don't currently hold office from altering the status quo too much. There are lots of us that think things are pretty good as is. Therefore, when voters vote, there's a whole host of concerns. I'd venture that very few Americans want ambitious policies towards certain issues. Especially, it seems, the progressive cockamamie that keeps seeming to take center stage in the Democratic Party and the nativist economic interventions that the Republicans seem fond of these days (getting into trade wars, raising tariffs, etc.)
Hence votes for gridlock.
