The Tea Party Convention is over. But the war it started is apparently just getting under way. Yesterday, Bill Hemrick, a conservative fund-raiser and the founder of the Upper Deck baseball trading-card company, sued the for-profit convention's organizer, Judson Phillips, in Williamson County Circuit Court in Tennessee, in a dispute over Sarah Palin's speaking fee. When Palin agreed to deliver the keynote address at the convention, it put the event in the news. And it was Hemrick, all agree, who provided the $50,000 down payment for Palin's $100,000 speaking fee.
