[EL] 2008 to 2012 what happened to MO and IN?

[Doug Hess]

I know this is not a psephology list, but I wonder why MO and IN are
viewed by many to be strongly Romney states. Granted, IN going for
Obama in 2008 was surprising (at least to me, and I suspect others).
And MO in 2008 was won by McCain by the skin of his teeth. But why are
both states considered out of Obama's reach now (see Nate Silver's
summaries of polls and some predictions in the link)?
