Gerald F. Seib has this Wall Street Journal article, noting that only 24 U.S. House districts last month voted for one major party for President and for the other major party for U.S. House member. However, the article notes that the election returns aren’t final and there are seven races in which the calculations might yet change.
Of the 24 districts, 15 voted for President Obama and yet elected a Republican member of the House; 9 voted for Mitt Romney and elected a Democrat to the House. Thanks to PoliticalWire for the link.
Those who advocate that each U.S. House district should elect its own presidential elector should note that if their plan were in effect, Romney would be elected, even though he lost the national popular vote by four percentage points.
