Since 2000 there have been over 90 attempts by the states to change the allocation method for selecting Electoral Votes. All have failed or never reached a vote. But a trend is developing. Most attempts have been to award EV to the winner in each Congressional District (the ME and NE method). But in 2005 almost as many attempts were made to award EV in proportion to each candidates share of the vote statewide. The latter method could result in awarding EVs to third party candidates, especially from the larger states like CA where a candidate with 2% of the vote would get an EV.
Here is a table of reform methods tried and failed in the states over the last 5 years. Not surprisingly, 2001 was a big year for reform attempts:
2001 2002 2003 2004 2005
At large ->District 25 13 4 9 9
At large ->Proportional 4 3 1 1 7
District->At large 1 1 1 0 0
A few oddities of note: in 5 yrs NY has failed to vote on even a single one of over 15 Electoral College reform proposals.
NE has failed 3 times to go back to the at large methods, ME has not traied to change.
Data comes from a national database that tracks bills in the 50 State Legislatures:
