I assumed it was because they were gonna do Miz/Ziggler last and have an emotional finish with Ziggler losing, but given that they didn't do that, the other thing I heard was that they did it because of the debate being on tonight.
I thought it was a good show, though. The World Title match was great, although I didn't like the finish. Cena losing to a chair shot to the back, even after taking damage throughout the match, seemed weird, given it's Cena. Miz/Ziggler stole the show for me. Those two have been amazing together recently. Orton/Bray was pretty good (AND LUKE HARPER IS BACK, UHHHHHNNNNNNN). The rest of the show was, at the least, decent to me. Usos are great as heels, the two women's matches were alright, nothing bad but not amazing, and Baron/Swagger was alright. Aside from the weird match placements, which, again, I assume are attributed to the debate, it was a solid show.
