At a New Hampshire rally on Monday, Sarah Palin trod the line between divisive attacks on President Obama and calls for unity in the Tea Party movement. “We don’t have time to be bogged down in internal conflicts and friendly-fire conflicts,” she told a crowd of about 1,000 in Manchester. “We need to grow this movement.” The remarks may have been a reaction to a group of Tea Party affiliates that protested a speech yesterday by Republican candidate Mitt Romney. Meanwhile, Palin stayed mum on her own potential candidacy. “I appreciate your encouragement,” she said when the crowd yelled for her to run.
