Now that Doug Hoffman has conceded, the only question is who to blame for his spectacular loss of a seat Republicans had held for 120 years.

Some teabaggers are already blaming the NRCC, because they chose the local popular candidate who would've held the seat for the GOP, and so they suck. Everyone knew that importing a rigid Glenn Beck-ideologue to a moderate northeastern Republican district was a sure-fire path to victory! We can assume Hoffman will be back next year, so maybe he'll 1) move into the district, and 2) maybe learn a thing or two about its needs before he runs again.

While I haven't seen it yet (too tired to look), I'm sure some establishment Republicans will blame the loss of a sure-fire hold to the outsiders who flooded in -- from Sarah Palin, to Tim Pawlenty, to Glenn Beck, to etc, etc.

But the real reason Hoffman lost? ACORN's ingenious broken bottle gambit.

It works every time.
