If Third Parties Had Voted As A Block.

If Third Parties Voted as a Block for one of the Two Major Candidates.

So let's open up the question and explore what would have happened if all third party voters had voted in unison for either Bush or Gore.

Again, we purge the states where either of the two got 50% or more. That leaves nine states where it MIGHT make a difference -- Florida, Iowa, Maine, Minnesota, Nevada, New Hampshire, New Mexico, Oregon, and Wisconsin.

By definition, those states were the ones where the number of votes third-party candidates received was equal to or greater than the difference in vote numbers between Bush and Gore: Florida (35 electoral votes), Iowa (7), Maine (4), Minnesota (10), Nevada (4), New Hampshire ((4), New Mexico (5), Oregon (7) and Wisconsin (11).

Out of those nine, Gore won Iowa, Maine, Minnesota, New Mexico, Oregon, and Wisconsin, for a total of 44 electoral votes.
Florida, Nevada, and New Hampshire went to Bush, for a total of 33 electoral votes.

The actual electoral vote count was Gore 266, Bush 271. If every single third-party voter in America had voted for Gore instead, the electoral vote count would have been Gore 299, Bush 238. Gore would have won.

And if every single third-party voter in America had voted for Bush instead , the electoral count would have been Gore 222, Bush 315. Bush would have won.
