A Tea Party Defense From Mary Frances Berry?

Mary Frances Berry talks Tea Party in Politico:

Tainting the tea party movement with the charge of racism is proving to be an effective strategy for Democrats. There is no evidence that tea party adherents are any more racist than other Republicans, and indeed many other Americans. But getting them to spend their time purging their ranks and having candidates distance themselves should help Democrats win in November. Having one’s opponent rebut charges of racism is far better than discussing joblessness.

Something to think about.
