If the Presidential Election used Instant Runoff Voting in past elections?

Here's what I get for '92 if we allow Bush to win states with a difference of 4 points or less and Clinton to take the rest.

Clinton 309
Bush 229

Why do you do that?

Simplicity, mostly.  I agree that most of Perot's votes were anti-Bush votes, but I think a certain number of them were basically conservative votes that were not inclined to go for Clinton.  So, I just allowed states that fell within the MoE to break for Bush, and gave the states outside the MoE to Clinton.  Of course, it's entirely possible, given the results in '96, that Ohio (particularly since Glenn won his Senate seat that year), Louisianna, Kentucky and Tennessee would have gone for Clinton anyway in '92, though I don't think Georgia or Montana would have.  In this case the map would look like this:

Clinton 342
Bush 196

All reasoable points.  Here is a final map for '92.

Clinton  323
Bush     206
Perot        9
