At some point there maybe a major change that will impact the procedure of allocating the EC votes within each state. If it was in place today nationwide and assuming the current make up of the House held and each district went the way it currently is represented [233 - 202] then it would almost assuredly place a democrat in the Presidency.
The congressional-district method of allocating electoral votes provides for EVs to go to the presidential candidate that carried the district in the presidential election, not to the presidential candidate of the party that won the House election. See my post #51 for a breakdown of how President Bush would have won in a landslide in 2004 had a congressional-district method been in place in every state (and how he would have won even had he gotten 3% fewer votes and John Kerry gotten 3% more votes).
