Frankly, I think that this presidential election looks exciting only on the surface. The way the field of candidates is set up I would be extremely surprised if the Labor ticket didn't win very handily. DemPGH/Windjammer essentially have a lock on the left-wing vote. Indeed, I can't think of a single left-leaning voter who wouldn't vote for them when given the choice between a ticket made up of two firmly left-wing Atlasians and other tickets that consist of a moderate leftist and a libertarian on the one hand (Sirnick/Dallasfan) and two centrists on the other hand (Winfield/Andrew).
What does the voter base of SirNick/Dallasfan and Winfield/Andrew look like? Well, the former may count on the support of what has remained of the TPP, a party which is probably on its deathbed (again), and a highly enthusiastic but small libertarian party, the D-R. You may throw in a few independents, but that's it. Therefore, I expect Sirnick/Dallasfan to do well on second preferences, but that's probably going to be worthless. If Winfield/Andrew remain the ticket that's perceived as the most right-wing, they will get a very high number of conservative and center-right votes, which, considering the fact that those voters represent about 30% of the Atlasian electorate, should be enough for the final round. However, that's obviously not going to be enough for them to get 50%+1 of the vote.
TL;DR: DemPGH/Windjammer will probably win the election with about 55-60% of the vote. I wouldn't mind if I were proven wrong, though.
