Sarah Palin continued to hint at a possible run for the presidency on the eve of her big Tea Party speech in Indianola, Iowa. The former Alaska governor told reporters at a Des Moines suburb yesterday that “there's room for more” candidates in the Republican primary, but didn't say whether she was talking about herself. She went on to pose for pictures with supporters inside a restaurant, as people chanted “Run, Sarah, run!” Aides have said Palin is unlikely to make her presidential intentions clear in today's speech. Real Clear Politics says Palin will attack “crony capitalism” in her speech, a veiled attack on Texas Gov. Rick Perry.
