A TV blog has the overnights

The Obama-mercial was fairly highly rated across the three broadcast networks (CBS, Fox and NBC) in the early metered market numbers. Between the three networks it scored an impressive combined 17.8/29 (household rating/share).

If ABC truly hoped that by being only scripted programming on broadcast for 8:00pm-8:30p, it would help out Pushing Daisies, that plan went awry. My guess is ABC was more likely just looking to burn off an episode. Daisies scored a 4.2/7, pretty much the identical rating it had a week ago up (4.2/6).
