My thinking is they are on the right track, but it would be nearly unprecedented for their model this time to be correct. That said, the polls mostly use 2008 results and aren’t realistic, which is what the site is trying to correct. I would guess maybe GOP +1 (as Gallup shows) or slightly Dem, maybe Dem +2 max.
2008 had people who don't vote, never voted, vote in spectacular numbers.
Every axiom of electoral polling states that people will revert to their usual voting behavior absent the motivation to continue. Every number to date says that motivation is not there: Amish are down in interest, Jooz are down in interest, maybe the Sandra Slutz contingent holds steady, while the married middle class is mad and motivated for Mittens.
