It's looking even more likely today that Hillary Clinton is going to put her hat in the 2008 presidential ring. She's hired a veteran national political fundraiser.

Phil Singer, a veteran of Sen. John Kerry's 2004 presidential campaign who most recently was spokesman for the Democratic Senatorial Campaign Committee, will join the Clinton communications team, her senior adviser Howard Wolfson said.

Wolfson cautioned that Clinton may still decide against a run but that Singer would play a senior role if she becomes a candidate, as expected. "I called him the day after the election," Wolfson acknowledged.
