Crunching numbers like only he can, Nate Silver conceded last night that Scott Brown is the three to one favorite to win today’s special election in Massachusetts. Silver also reminded readers that Martha Coakley’s slim, 25 percent chance of winning is still a 25 percent chance of winning.

The wattage behind that ray of hope is boosted by the Coakley camp’s internal polling, but diminished by a late, perhaps the last, external poll released yesterday.

So the easy-money bet on the outcome goes to Brown, although it might be even easier to win by predicting how all of this will be perceived and reported tomorrow. My (not-rocket-science) guesses:

A Brown victory (no matter how modest or grand) will be portrayed as a repudiation of Obama and the beginning of a very painful mid-term cycle for Democrats.

In contrast, a Coakley victory will be viewed by many as an upset, providng a final splash of irony in a race that has been soaked in irony — none of which will stop pundits on the right from portraying her “almost defeat” as a repudiation of Obama and the beginning of a very painful mid-term cycle for Democrats.

There, now you don’t even have to read tomorrow’s post-election analysis. I just summarized it for you, and if it deviates much from that summary, I’ll be very surprised. In fact, the only outcome that might make the themes in tomorrrow’s coverage difficult to predict would be a landside win for Coakley. Granted, that’s not going to happen, but if it did, we’d at least have something interesting (i.e., entirely unexpected) to read and write about tomorrow.

UPDATE: My bad. I forgot another scenario that would make tomorrow’s coverage more interesting, namely: the too-close-to-call, endless-recount scenario. Even then, while entertaining (for some) to read, the themes of such coverage would still be predictable, with each camp arguing the merits (ad nauseam) of either a prompt seating of their candidate or a prolonged recount process.
