Yeah, this has been going around for months. Supposedly, they have a perfect track record of picking the eventual nominees of each party going back to 1975, but when I looked, I could only find examples of their mock poll results published online for 2007 and 2011. I wasn't even able to find that specific claim on WIU's site.
In their defense, I don't think they ever claimed that their electoral projections state-by-state are accurate (I believe those votes are determined based on the student voters' states of origin), but I have had more than one infuriating conversation on social media with Sanders supporters over how there's no way in hell that Sanders wins WY and a dozen other states while losing IL, MD & HI.
At any rate, I think they're going to be wrong this cycle, even if their track record of accuracy goes back as long as some have claimed.
I was thinking the same thing about the student's home states, but Illinois is red and it's Western Illinois University. Assuming the majority of students are from Illinois other than just a handful, I wouldn't think Bush would be chosen over Bernie. And I don't see any explanation for PA just being blank and like I said the EV totals don't even match the map.
