What's interesting is that the *only* places you can even read about this are on some minor conservative web sites. Not a single mention of it on CNN that I can find. Strange...
How much you want to bet that if there'd been huge crowds, it would have been covered? After all, they *were* there, and did write a story about the group on the day of the signing. Kinda strange that they didn't mention the signing, but only detailed the group heading out (while making a point to mention the large numbers of supporters they had earlier in the year).
Bias? You decide.
