Presidential Results by Congressional District

Clark Bensen of Polidata writes:

As the president was reelected in 2012, the election results indicated a reduction in the overall support for President Obama, even though areas of the relative strengths for both major parties remained about the same. The reduction of President Obama’s overall percentage of the vote from 53.7 in 2008 to 52.0 in 2012 also resulted in a majority of districts voting for Romney.

...

While this 226 to 209 break is quite near the breaks for 2000 (Bush 228 to Gore 208) and for 1960 (Kennedy 204 to Nixon 227), this represents the first time since 1960 that the winner of the election did not win the popular vote in a majority of the congressional districts. Also, the number of ‘turnover’ or ‘split’ districts has hit a low point compared to recent elections at 26: 17 Republicans in the House are in districts carried by Obama and 9 Democrats are in districts carried by Romney.

Of course, there were two other factors at play in how many congressional districts were carried, or ‘won’, by each nominee: a) the capture of the U.S. House by the Republicans in the 2010 elections; and b) the redistricting cycle following the 2010 census.
