In hindsight, Indiana going for Obama isn't that shocking

[Wiz in Wis]

While I agree that it would be surprising for Obama to repeat in Indiana in 2012, it is also fair to say that the Republican dominance of Indiana is history too. Once a state swings, certainly so substantially, it hardly ever reverts back... look at West Virginia... Once it made up its mind to vote Republican in 2000, it never looked back... same with any other state where demographics are not changing rapidly. For the same reason, the Republicans can probably count on New Hampshire going Dem for the next few cycles too.

Once a majority of Indianan's voted for a Dem, they will be open to the concept, if not likely to do so systematically. Combine that with generational and demographic (black and hispanic) trends, Indiana is now a swing state for the forseeable future.
