Not having the 2004 presidential results map by CD yet, here's the one for 2000:
Under the Nebraska/Maine system, the result would have been:
Gore: 13 votes (11 CDs, 2 AL)
Bush: 10 votes
With the Colorado system, Gore would have got 12 votes, Bush 11.
Obviously it would be nice to do a similar analysis using the current 21 EVs for PA, but we'll have to wait for that I guess.
Thanks for the info.
I estimate that Bush would have carried a majority (12+/- 1) of the Congressional Districts in Pennsylvania in 2004.
