I am not an "America bad" type of fellow, but US democracy is clearly reaching a local minimum. I suspect "never more functional" is an idea with which even your representative would disagree. There are multiple major issues that Congress should have addressed decades ago and instead they've only become more intractable. The country is more than its government, but the core democratic component, Congress, simply gets very little done. I do not think it can go much longer before some series of events forces broad compromises and realignment.
