House District Demographics

Previous posts have discussed the African American and Hispanic vote in congressional elections.

Thanks to Dave Wasserman at the Cook Political Report, we now have demographic stats on current House districts.

There are now 111 majority non-white Cong. districts, surpassing 25% of all CDs for 1st time. 97 are held by Dems. docs.google.com/spreadsheet/cc…— Dave Wasserman (@Redistrict) February 20, 2013 

The only 2 GOPers repping 80%+ non-white districts? #CA21 David Valadao (R) & #FL27 Ileana Ros-Lehtinen (R). docs.google.com/spreadsheet/cc…

No Republican represents a district that is more than 35.08% black. That is the percentage in Rodney Alexander's Louisiana 5.  Most of the other districts with a substantial black percentage are in the South, where voting is highly polarized along racial lines.  Alexander, however, has some history of actually winning a fair number of African American votes.
