This article details the involvement of the Koch Brothers with the Tea Party. It is a long and very worth your time and effort to read and digest. If you want to understand the Tea Party, where it came from, and how it is funded read this entire article. There are some key names in here that show up over time. Remember them and when you read other articles in the future make the connections.
Personally, I have mixed feelings about the Tea Party, the Koch brothers and the agenda being pushed. I embrace many Libertarian values and much of their agenda. However, we should all understand where the messages are coming from, who is crafting them, their goals, and who is ultimately behind these seemingly disparate groups that are tied together in many complex and interesting ways.
Strongly recommended use of your time to read and understand.
