Obama was the choice of 32 percent of likely Democratic caucusgoers, up from 28 percent in the Register’s last poll in late November, while Clinton, a New York senator, held steady at 25 percent and Edwards, a former North Carolina senator, was virtually unchanged at 24 percent.
The poll reflects continued fluidity in the race even as the end of the yearlong campaign nears. Roughly a third of likely caucusgoers say they could be persuaded to choose someone else before Thursday evening. Six percent were undecided or uncommitted.
