What has the TEA party movement done to indicate that it has lost it's integrity? I would suggest that the exact opposite has occurred. Look at Arizona. JD Hayworth was the Tea Party's candidate. He then made it clear that he was as corrupt as many in Washington with his ads pushing big government tax give-aways and the Tea Party abandoned him.
Just because neither Didier or Akers was able to beat Rossi doesn't say anything about the Tea Party. However, refusing to vote for Rossi because he doesn't stand for 100% of the things that you do doesn't accomplish anything. Get behind Rossi, see how he does for the next six years (which is guaranteed to be better than Murray even if not where you want it to be) and then run a more conservative candidate against him in the next primary. We have been losing our country since FDR, we aren't going to get it back in one election.
You also stated that the R's were just as culpable as the D's. I agree to a certain extent but let's check the record. The R's, in the first six years of Bush, managed to rack up less debt that the D's have racked up in the first year and a half of Obama. Since the Tea party is about Taxes, that is a huge difference.
I'm not excusing what the R's and Bush didn't do. I wanted to see rollbacks of federal programs, elimination of unconstitutional programs and laws, reduction of taxes and debt. I was very disappointed in that six year window and the lack of results. But the last two years have clearly defined the difference. The D's are adding debt, federal employees, and federal programs at a rate that makes the Bush years look like a handbook by John Stuart Mill. Was the first six years terrible? Yes. Could it have been worse? Just look at the last two years.
And to return to the current topic of Dino Rossi, his record as a State Senator was one of fiscal responsibility. I don't like his namby pamby ads, each of which seems to include the phrase "while protecting the most vulnerable among us", which I think is a huge cop out to a serious analysis of the Constitutionality of various federal programs, but he has a much more conservative record than Murray and I believe that we can keep him on the right track. If not, it's better than Murray no matter what, and out he goes in 2016.
