At a internet startup, two Harvard students through their start up QUroum decided to do the numbers on women as dealmakers in the US Senate.

They analyzesd legislative data and put number-crunchers to work. It’s a little bit wonky, but stick with it. Over the past seven years, the Quorum analysis found, the average female senator co-sponsored 6.29 bills with another Senate woman, while the average male senator co-sponsored 4.07 bills with another Senate man.

Over all, women were far more likely than men to work across the aisle. Quorum found the average female senator co-sponsored 171.08 bills with a member of the opposite party; for the average male senator, that figure was 129.87.

“Women are not only introducing more legislation over the last seven years, but they are also getting more support for that legislation, getting more bills out of committee and getting more enacted than their male colleagues in the U.S. Senate,” said Quorum’s co-founder, Alex Wirth, a former White House intern and one-time Senate page who comes by his interest in politics naturally. (Timothy Wirth, the former Democratic senator from Colorado, is his great-uncle, and his parents met on a Wirth Senate campaign.)

Quroum draws data  from publicly available information, including congressional bills, votes, news releases, tweets and floor statements. The numbers, of course, do not explain why female senators appear more collegial and productive, though Mr. Wirth notes that the women of the Senate have long held their own bipartisan dinners, which could have something to do with it.

Mrs. Merkel also makes more deals than her male counterparts!
