Soetoro-Ng plans to fly from her home in Honolulu to Chicago and then strike out for such key early states as Iowa, New Hampshire and South Carolina. It’s her first real foray into politics—though she admits bashfully to taking part in some protest marches as a teenager. Don’t look to Soetoro-Ng to help Obama start throwing punches, as he’s promised, at his rivals. Her motherly sensibilities seem far afield from the instinct for the political jugular. Requests to engage on even mildly controversial topics in the campaign are politely rebuffed. The toughest thing she’d say about her sibling? “He could be bossy, but he was never mean. He still is.”
