Eh? I'd also have a problem with your listiing of George McGovern, among a few others overall given that some are irrelevant and such, but when considering your biases and priorities, you still have a dislike for Robert Taft?

In any case, the worst human being (of importance) in American politics is probably the one occupying the Oval Office or otherwise overseeing things, regardless of party. Something something morality and all that.

Taft was anti-New Deal, anti-labor, and anti-safety net--basically, a reverse Robin Hood.  McGovern was so liberal he wore the term as a badge of honor, even after it became a "dirty word" in the 80s.  He also led the senate committee in the late 70s that encouraged the consumption of trans fats as a "healthier" alternative to saturated fats, thus contributing to America's epidemics of obesity and heart disease.

Al Franken, Howard Dean, Justin Amash, Barbara Boxer

You are a truly bizarre individual. Three of those are fairly bland, noncontroversial Democrats. Has Dean even done anything since 2004?

Al Franken is a dick, and Barbara Boxer is a huge b[inks] but neither of them are remotely horrible people in the tradition of the Atlasian term "HP."

No, because at Atlasian HP simply means a Republican.
