Jill Lawrence writes for the National Journal: “Five senators in any small room will set the atmosphere crackling with authority and power, and that was true here despite the conspicuous absence of testosterone. You don’t get to become or stay a senator without sharp political-survival skills, and the cool self-assurance that you belong in one of the world’s most exclusive clubs. Most of the women also believe they make special contributions to the Senate—in the issues they highlight, in their collegial style, and in the close-knit network they have formed, despite their differences.”
