The TAKS effect: Every state that starts with "T", "A", "K" or "S" voted for McCain. There are 10 such states and they comprise 98 electoral votes. McCain won those states' popular vote by a margin of 14%.
Eliminate TAKS, and the rest of the country voted for Obama by a 10% margin (compared to the 6% for the whole country). The electoral vote count is 349-64 (with 27 yet to be determined).
The KKK effect: Every state with a "K" in its name voted for McCain. There are 8 such states and they have 41 electoral votes; McCain has won 40, while one from Nebraska is still uncertain. McCain won those states by 19%.
Eliminate KKK, and the rest of the country voted for Obama by an 8% margin, with the electoral vote count is 349-122 (with 26 yet to be determined).
Eliminate both TAKS and KKK, and Obama wins by 11% and 349-50 electoral votes (with 26 pending). Additionally, the 55-40 advantage in the Senate becomes 49-21, and the 245-157 advantage in the House becomes 219-121. (Pending seats not counted.)
Well, Mr. President, you may say there are no red states and blue states, but there sure are TAKS states and KKK states, and they don't like you very much. The rest of the country looks pretty normal.
UPDATE (many months later): Oops, not every state with a "K" voted for McCain. Thanks to Samer for correcting me.
