History

Historical Context

Barack Obama’s surprise win in the Jan 3, 2008 Iowa Democratic caucus—where he captured 38% of the vote and 16 delegates amid a record 239,000-person turnout—propelled him to national prominence. That early grassroots surge showed how strong organization can create sizable primary leads, a pattern echoed in the 2026 Massachusetts Senate race between incumbent Ed Markey and challenger Seth Moulton.
