E.J. Dionne:  “The Tea Party is nothing new. It represents a relatively small minority of Americans on the right end of politics, and it will not determine the outcome of the 2010 elections.  In fact, both major parties stand to lose if they accept the laughable notion that this media-created protest movement is the voice of true populism. Democrats will spend their time chasing votes they will never win. Republicans will turn their party into an angry and narrow redoubt with no hope of building a durable majority.”
