Sarah Palin to Headline Tea Party Convention

Sarah Palin will be the headline speaker in the nation's first-ever Tea Party convention next month in Tennessee, raising the specter of a spin-off political party already laying claim to a presidential candidate. A generic “Tea Party” is already more popular than either Democrats or Republicans, while Palin rivals Obama in popularity in a new NBC/Wall Street Journal poll. "Tea types can either blossom into a Perotista-style third-party movement or be subsumed to some degree by the GOP," notes Howard Kurtz in the Washington Post.

Either way, Tea Party supporters will wield significant clout in upcoming elections by tapping into discontent with the Democratic Party and threatening to purge moderates from the GOP, experts note. Enter Sarah Palin, who never stopped campaigning for herself. "This is perfect for her, made for her," Emory University politics professor Alan Abramowitz tells the Christian Science Monitor.
