Imagine an alternate universe where we had Watergate-style hearings when Pelosi/Reid took over in 2007, or when the Obama administration started in 2009. In some circles, some people wanted that, and I think rightly or wrongly politicians decided it was not worth it. Easy to forget now, but it was certainly in political discourse 6 to 9 years ago.
