I've come to think of said "dreary DATA driven projections" as a little like the psephological equivalent of talking GPS: it may "get you there" (seemingly), but it's no match for well-tuned navigational skills--or what London taxi operators call "The Knowledge". It's an easy crutch; that's it.
Yes. And the thing is, when an election is fluid as this (especially given the possibility of all sorts of freakish results on low poll shares...) if the data-driven projections
are right it won't be because of their inherent accuracy, but luck...
