I Googled McCain Crowds in an attempt to find the article about how the McCain event last week where they reported there were 23,000 was later adjusted to 20,000 and today they admitted it was more like 8,000.
What I did find was these headlines and links:
McCain Minus Palin Equals Smaller Crowds

McCain-Palin Crowd-Size Estimates Not Backed by Officials
By Lorraine Woellert and Jeff Bliss
Sept. 13 (Bloomberg) -- Senator John McCain has drawn some of the biggest crowds of his presidential campaign since adding Alaska Governor Sarah Palin to his ticket on Aug. 29. Now officials say they can't substantiate the figures McCain's aides are claiming.
McCain aide Kimmie Lipscomb told reporters on Sept. 10 that an outdoor rally in Fairfax City, Virginia, drew 23,000 people, attributing the crowd estimate to a fire marshal.

In recent days, journalists attending the rallies have been raising questions about the crowd estimates with the campaign. In a story on Sept. 11 about Palin's attraction for some Virginia women voters, Washington Post reporter Marc Fisher estimated the crowd to be 8,000, not the 23,000 cited by the campaign.
