John McCain / Mike Huckabee vs. Mark Warner / Russ Feingold??
I think it would be a very interesting race, though not a north/south flip.
Warner could win AR if it weren't for Huckabee.
McCain could win WI if it weren't for Feingold.
All the other red/blue states would fall into place 2000 and 2004 style except for a few: I think McCain can take NH in this scenario and possibly OR.
Iowa I wasn't sure...flip a coin I guess.
Also, CO would be a lock for McCain, and so would the rest of the southwest.
I don't think McCain could ger any northeastern state besides NH.
266 Warner, 265 McCain. how would Iowa vote?
Considering people vote for the top of the ticket rather than for the bottom of the ticket, I would say Mark Warner would have the better chance of winning. With your map, I would keep everything the same and move Iowa to the Democrats due to its northeast border with Wisconsin. Like you said, though, Iowa could flip either way.
