It is always amusing when people first discover that people on the internets are mean. For some politicians, especially, it's probably the first time they've really come into contact with people not showing respect or deference. Of course these conversations have taken place in bars and living rooms, but now they can be "overheard."
I remember one member of Congress complaining about things that right wingers said on the internet. The complaint was made with good humor, mostly, but I could tell it stung. Just wasn't used to it.
