What Tea Party “success” was the WashPost referring to?

This was from a couple days ago but I think it's still worth taking a look at. And no, I'm not trying to be facetious with the headline question. I'm genuinely curious what the Post was referring to here:

If imitation is the highest form of flattery, the “tea party” movement must be honored. In an effort to replicate the tea party's success, 170 liberal and civil rights groups are forming a coalition that they hope will match the movement's political energy and influence.

I realize there's been the agreed-up Beltway CW for moths now that the right-wing GOP Tea Party has become hugely influential and reshaped American politics with its grassroots uprising. And the D.C. press corps has smothered all-thing Tea Party in run-away coverage.

But I'd still like to hear about the Tea Party “success.” The Tea Party, of course, failed in stopping Obama's health care reform, a legislative initiative that Tea Party leaders and supporters rallied against. Indeed, you could argue that the Tea Party was formed specifically to make sure health care reform was not passed by Obama. But the Tea Party failed.

The Tea Party also failed in stopped Obama's stimulus package, as well as the White House's push to bail out Detroit automakers. Currently, the Tea Party is in the process of failing to stop Elena Kagan from becoming a Supreme Court Justice.

If we go back to last year, the Tea Party and its supporters set their sights on the N.Y. 23 Congressional race and managed to turn the red district blue for the first time in nearly 150 years. And okay, yes, Republican Scott Brown shocked a lot of people by becoming Massachusetts' newest U.S. senator. But after his victory he quickly distanced himself from the Tea Party and claimed the party was not responsible for his win.

You could argue that Sharon Angle in Nevada and Rand Paul in Kentucky are two senate candidates who clearly owe their primary wins to the Tea Party. You could also argue that, based on local polling, Angle and Paul are in the process of turning sure-fire GOP wins in Nevada and Kentucky into toss-up races.

And oh yeah, Tea Party rallies have become something of a joke, drawing increasingly miniscule crowds.

So I'll ask again. What was the Post referring to when it referenced Tea Party “success.”
