I was listening to BBC radio on my way home the other day (I have XM), and they were interviewing three people from the tea party at the rally in DC.
All three of them had very good points they brought up, and every one of them had an issue to talk about. You would have never seen that interview on mainstream media here in the US. They would have found the few people out of the thousands with misspelled signs, or yelling crap at people, and put that on the news.
The reason the Tea Party is going to be a real force in my opinion, is it's a party of only issues. If you were to go to one, and ask everyone why they were there, you would hear about taxes, or healthcare, or spending, or the war, or any number of other issues.
Almost no one would mention Obama, or the democrats, or the republicans. It's not about hate for a man or a party. It's about the issues. And when your fighting against someone who just wants to talk about the issus, it's very hard to win, if your not right. A smile and a good speech writer is not going to do it.
