'This groundbreaking research shows the value of having more women in Congress. Among other important findings, Volden and Wiseman clearly show that women more effectively build coalitions across party lines and focus more directly on getting things done. That has certainly been my experience throughout the past two decades, and it reinforces what I've said all along: we need more women in public office. The answer to the partisan gridlock that currently plagues congress can be found in a very simple question: where are the women?' Carolyn Maloney, United States Representative (Democrat - New York)
