When you're a democrat, you know you're candidate can't legitimately win so.....
Same thing happened to my husband and me when we *tried* to attend George W. Bush's inauguration in 2004. The hard-core leftists were blocking ALL security gates. We had legitimate tickets that we got from our Congressman for 2 seats at the inauguration, but we never were able to get in because of all the vile, unwashed commies. We ended up walking down the street to some hotel, and watched the inauguration on a TV in the lobby with some other people.
I'm sure it was all sweetness and light for Hussein's two inaugurations. Nobody on "our side" showed up in the hundreds of thousands to block entrances and gates, and create chaos for the event. I *hate* these people!!
