According to Nobel Prize winning economist Paul Krugman[2] [3], the ugliness emanating from the McCain campaign is the result of a few very wealthy people on the political right. It's an ongoing behavior that precedes the Clinton administration. These are the people who see anyone who disagrees with them as 'the enemy'. It raises political disagreement to the level of class warfare.

Krugman speculates that an Obama Administration will see an increase in this behavior and the likelihood of violence.[1] Is this the kind of America you want?

Liberals are often ridiculed for their 'understanding' behavior, but everyone has limits. Be very careful what you ask for.
