I hear ya'.
My daughter worked for Senator Tim Johnson from SD for a couple of years, as his top personal assistant. She got to know the members of the Senate pretty well.
My take away from her experience: there are many really good people serving as US Senators, more than most of us would think. There are also some awful ones, twisted and driven by narrow mindedness, superstition, fear, and bigotry, who see democracy as a tool to use and bend rather than a set of principles they must live by.
The one person she came away admiring the most, because of his consistent warmth, dignity, and respectfulness of others, was Corey Booker. He treated everyone the same, regardless of "rank," and has a way of listening intensely and seeking to learn new things.
She's an absolutely no BS person (spots hypocrisy 10 miles away and is rarely silent about it) (and yes, her adolescence was just joyful). So she's really hard to impress in this regard. I'm taking her experience and observations as legitimate information.
And yes,
@Tunescribe, I realize Booker represents New Jersey, and I've got no answer for you on that, other than perhaps it is the ultimate testing ground.
