In my view, 2008 was a fluke with a massive D trend. I think 2012 was a reset back to normal between 2004 and 2008. Probably many white conservative voters there who took the chance (and possibly because of Joe Biden) to vote for Obama because they were tired of the Bush administration. 2008 was a very motivating year for democrats.
I agree with you and would say Delaware is such a small state that it's easy for it to show trends and swings simply because of a change in voter turnout. It's just too small. Having said that, I'd like to see the GOP compete in Delaware early in 2016. Christie may not be a far fetched success there.
