Only about a quarter of the onlookers here have booze in hand, and the atmosphere seems cautiously optimistic.

Here’s the stage:

Cheers and a few whistles greet the news that Giffords is beating Graf in Arizona’s 8th District, and Klein over Shaw in Florida’s 22nd, and Hill over Sodrel in Indiana’s 9th, and Gillibrand over Sweeney in New York’s 20th.

But the older lady behind me is still gloating over Santorum getting, ahem, creamed.
