She represents a district that McCain won in 2008 and surely was aware that Republicans would be devoting considerable funds to defeating her. Nonetheless, she voted for TARP, cap and trade, the stimulus, and health care reform, and she still managed to retain her seat last year. That certainly merits some sort of mention.
Whoa. It sure does. More than those of us who don't study political science for a living (as Masket does) might recognize. In the aftermath of the last election, political scientists Brendan Nyhan, Eric McGhee and John Sides took a dive into the data and found that what hurt individual House Democrats most was votes on precisely those four bills:
We counted the number of these measures supported by each Democratic incumbent and then estimated the effect of this support on their election conditional on the partisanship of the member’s district (controlling for other factors). The simple answer: these roll call votes mattered. A lot. A Democratic incumbent in the average district represented by Democratic incumbents actually lost about two-thirds of a percentage point for every yes vote. Democrats in the least Democratic districts, such as Chet Edwards of Texas or Gene Taylor of Mississippi, lost about 4 percent for every yes vote.
