Using ridership data from the Washington DC Metrorail service, LGF’s Charles Johnson seeks a reliable means of judging attendance at September 12’s anti-Obama rally:
As Charles notes:
Two things: first, that unofficial estimate was apparently made at 9.43am, some hours prior to the rally’s peak. And second, comparing September 12, 2008, to September 12, 2009, won’t yield reliable information – because the first date fell on a working day (Friday), while the second was a Saturday. The Heritage Foundation’s Mark Kelly digs further into DC’s rail stats:
Considering various other factors, Kelly arrives at a tentative estimate of 313,000 to 433,000 – much lower than the extreme high-end figures (two million) Johnson dismisses, but far more believable than 70,000, which anyone who’s both familiar with Washington and spent considerable time at sports events among 70,000+ crowds (me) knows is ridiculously inaccurate.
