State Senator Mallory McMorrow leads trader consensus at 55% implied probability in Michigan's open Democratic Senate primary following Gary Peters' retirement announcement, driven by her internal Global Strategy Group poll from March 19-22 showing a 30%-25%-23% edge over Abdul El-Sayed and Rep. Haley Stevens amid 21% undecideds, plus year-to-date ActBlue dominance with $1.22 million from 55,000 small donors. El-Sayed's 32.5% reflects strong +38 net favorability and a competing internal poll lead, while Stevens' 13.5% trails as her support softens. Fundraising momentum and shrinking undecideds have propelled McMorrow ahead in this closely contested August 4 primary race among millennials offering contrasting Democratic visions.
