### So, How Much Sanity Was There in D.C. Yesterday? (Updated)

Which means we can, at last, estimate the size of the damned crowd. We'll use exactly the same figures for crowd density we used for the One Nation rally and the Beck "Restore Honor" rally:

 Estimate 10 square feet per person 5 square feet per person 2.5 square feet per person Maximum: 162,000 324,000 648,000 90 percent 145,800 291,600 583,200 75 percent 121,500 243,000 486,000 50 percent 81,000 162,000 324,000 Based on CBS news estimate 58,725 58,725 58,725 40 percent 64,800 129,600 259,200

The row labeled "based on CBS News estimate," by the way, is using the CBS figure of 87,000 for the Beck 8/28 rally to derive a number for square feet per person, and applying that to the Stewart/Colbert rally.

It's worth looking back at our table from the 8/28 rally for comparison.

 Estimate 10 square feet per person 5 square feet per person 2.5 square feet per person Maximum: 215,000 people 430,000 860,000 90 percent 200,000 400,000 800,000 75 percent 163,000 326,000 652,000 50 percent 108,000 216,000 432,000 CBS News Estimate 87,000 87,000 87,000 40 percent 86,000 172,000 344,000

Of course, we could have shortened this considerably: the Beck rally covered about 2.4 million square feet, while the Stewart/Colbert rally only about 1.6 million square feet.  In other words, we know from that alone that the Stewart/Colbert  rally was about  six-tenths as big as the Beck rally.

Back when I was an undergraduate at the University of Colorado, the common rumor was that Colorado had been left out of Playboy magazine's rankings of the top party schools because "it was unfair for professionals to be included in competition with amateurs."  (It wasn't true, and I presume lots of other schools had the same rumor; spare me from everyone's story of how it was really their school.)

But in much the same way, it seems a bit unfair to compare either the 9/12 rally or Beck's 8/28 rally with this one.  The 9/12 2009 rally was more or less ad hoc; Beck's rally was more organized, but still basically a rally.

But look at the Comedy Central "Sanity/Fear" rally.  As PJTV's Richard Pollock found out, it was very carefully organized, with limited press access -- or at least attempts to limit press access -- and with the announcement that video and photography was prohibited except for Comedy Central.

(On the National Mall?  Good luck with that, bunky.)

There was a big proscenium stage, with a lovely setup framing the Capitol -- as a sometimes theater guy, I really admired it, it was gorgeous -- and a large controlled area  behind the stage for performers and technical people. Professional sound set ups, with big name acts flying in for a few numbers.

Big name acts, extensive crowd control, rules against video or audio taping even with your cell phone, boring political speeches ... this wasn't a rally, this was a U2 concert!

And that tells us the real story: they held a rock/comedy concert, with pro acts including two of the hottest TV comedians around, and professional production, with free admission and with Arianna Huffington paying for bus rides -- and no matter what you think a "dense" crowd is, it was still only about six-tenths of Beck's open-air church service.

But the bearded guy really wasn't a bad imitation of Cat Stevens.  Not like the real thing, of course.  I wonder if he's thought of going pro?

Update:

Before this went to press, CBS News made their own estimate: 215,000 versus their estimate of 87,000 for the Beck rally.

To which I say "Oh, nonsense."

Their contractor, AirPhotosLive.com, it turns out, did at least publish an explanation of their methodology,.

AirPhotosLive.com is correct that trying to count oblique photos is unsatisfactory, which is why we don't: we use the oblique photos to get geography bounds on the crowd against landmarks, and then make a range of estimates using the Park Service's own standards for crowd density.

The Beck rally covered roughly 2.4 million square feet and by AirPhotosLive's own photographs large parts of that area were packed as densely as any overhead picture of Stewart/Colbert.  The Stewart/Colbert rally had, at most, about 6/10th the space -- 1.62 million square feet vs. 2.4 million.  For it to have had that many people, they would have had to be packed about 6.7 times more densely than the densest parts of the Beck crowd.

Not a chance. Not even if they were packed in olive oil.
