The House Of Unrepresentatives

John Sides argues that gerrymandering didn’t kill bipartisanship:

The most important influence on how members of Congress vote is not their constituents, but their party. This makes them out-of-step not only with the average American — the “broad-based public opinion” that Obama mentioned — but also, and ironically, with even their base. Members are more partisan than even voters in their party.

On the other hand, looking at immigration reform, Micah Cohen finds reason to believe that a Congressman’s constituents do make a difference:

[T]here is no guarantee that Republicans with a greater share of Hispanic constituents will necessarily favor reform. But three of the four Republicans in the House already negotiating an immigration bill with Democrats — Representatives John Carter and Sam Johnson, both of Texas, and Mario Diaz-Balart, of Florida — come from districts that are more Hispanic than the average Republican-held Congressional district.
