In this Sam Stein article posted on Huff Post, Stein tells what it was like being surrounded by Clinton supporters. 

To summarize the piece, Stein recounts statements from Clinton supporters such as:

"[Obama] is a socialist! You know what the Nazi Party was before it was the Nazi Party? It was the Socialist Party."

Also: "Would you rather have a president who had an affair [Bill Clinton] or one who was a murderer [Obama]?"

Stein also said that he had conversations with some of the supporters who showed contempt for Obama and the media.  They went through a list of websites they have blacklisted, including Huff Post.  When he told them he was a reporter for the Huff Post, they stopped talking to him.  He went to eat he lunch, only to be serenaded by chants of "Huff Post sucks, Huff Post sucks!"  Later they chanted "Fox News fair and balanced, Fox News fair and balanced.

At the bottom of the article is video of a Clinton supporter who was kicked out.  If you watch the coverage, you may recognize her voice yelling about Iowa and New Hampshire.  She says that Obama is "an inadequate black man."
