A number of people in the intellectual world did, or at least wrote articles purporting to explain why it was more than remotely possible.

The relatively new set of people in the major media trying to play the poll-based mathematical prediction game that Nate Silver started with 538 who weren't Nate Silver undersold the chances of it happening because they made the naive mistake assuming that deviations from polling averages between states were independent of each other rather than, as historical analysis of the type Silver does would show, tightly correlated. But “media outlets want what Silver does but can't afford to pay to have Silver, or anyone with anything like his level of skill at what he does” doesn't represent the “intellectual class”.
