A basic perception of goodwill and competence?
The Supreme Court has a very narrow mission statement, and it generally executes on it well.
Congresspeople sabre rattle on TV, submit symbolic legislation with poison pills and take turns abstaining on legislation they don't want passed but their constituents do, and hide whatever they want to pass in unrelated legislation (budgets, usually). They eagerly devolve every responsibility they can to the executive branch, and seem incapable of voting against their own or the intelligence community's interests.
The only principled one seem to be single-issue legislators who couldn't tell the ass-end of a horse from its head if it was unrelated to their obsession.
During depositions they spend more time chasing soundbites and executing partisan jabs than trying to extract any information in the public interest.
Many of them seem to care more about the rest of the country than they ever could about their district or their states.
