Just heard on Fox New Sunday, a claim that the National Park service tweeted out a crowd size. My understanding the Nation Park does not track crowd size.
The Park Service used to always underestimate Tea Party crowds and overestimate liberal crowds. They are part of the swamp.
They want so much to be men, they out-swagger the average guy!
One important point that is not being emphasized is that the lawns in the Mall were covered with tarpaulin for the first time during an inauguration, thus giving the impression of empty space. CNN, for one, showed that empty space distinctly in their shots of the crowds. The lawns are usually cordoned off and devoid of crowds anyway!
