Changing the rules could change the end result, but proposed changes in some states to the method of selecting Presidential electors could favor the GOP, at least the way things are now.
For as long as anyone can remember, 48 states have allocated electors on a winner take all system. Two states Nebraska and Maine have allocated by Congressional district.
In fact in 2008, Barack Obama lost Nebraska by a considerable margin but still got one electoral vote because he narrowly carried the state's Second CD based in Omaha.
An effort is afoot in Virginia and other state's to switch to that system, which in some cases could mean the candidate getting a majority of a state's popular vote would get a minority of the electoral vote.
This is bringing cries of foul on MSNBC where commentator Ed Schulz labed the effort, you guessed it, "racist".
Who carries a given CD isn't necessarily significant to voters making their choice for national office. After all, most CD's are of such a shape, nobody identifies with the blob on a map.
This move is clearly a gambit to better position the GOP for 2016, so if they lost say a VA or PA, they still get electoral votes. By cherry picking the states where it could help them (and ones where they could get it passed) Republicans could make the system more complicated nationally but more friendly to them.
Of course they could just nominate a candidate capable of winning a few more states as well as the national popular vote which they lost this time 51-47.
