Haley Stevens polls have become one of the most closely tracked numbers in American politics this election cycle, as the four-term Michigan congresswoman faces progressive challenger Abdul El-Sayed in the state’s high-profile Democratic Senate primary. With voting taking place on August 4, 2026, multiple surveys released in the final weeks of the race show a wide gap between the two candidates, though the picture has shifted several times over the course of the campaign. This article breaks down where Stevens stands, how the numbers have moved, and what the polling may mean for the outcome of Michigan’s most closely watched primary of the year.
Who Is Haley Stevens
Haley Stevens represents Michigan’s 11th Congressional District and has served in the U.S. House since 2019. She built her political career around manufacturing policy, economic development, and her prior role helping oversee the Obama-era auto industry task force. In the current race, Stevens is running to succeed retiring Senator Gary Peters, positioning herself as the moderate, establishment-aligned candidate in a primary that has increasingly become a proxy fight over the direction of the Democratic Party. She has earned endorsements from Governor Gretchen Whitmer, Senator Gary Peters, and former Senator Debbie Stabenow, along with backing from Senate Democratic leadership.
Her rival, Abdul El-Sayed, is a former Wayne County public health official who ran for Michigan governor in 2018. He has campaigned on Medicare for All and has drawn support from prominent progressives including Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez. The primary has been widely described as a test of whether Democratic voters are leaning toward centrist continuity or a more progressive, insurgent direction ahead of the 2028 presidential cycle.
Latest Polling Numbers
Recent polling has largely favored El-Sayed heading into primary day, though the surveys have varied in size of the lead. An Emerson College Polling survey conducted July 26–27, 2026, found El-Sayed ahead of Stevens 54% to 39%, with 6% undecided; when leaners were included, that margin widened to 57% versus 41%. The same poll showed a pronounced generational divide, with voters under 50 favoring El-Sayed by more than 40 points, while voters over 60 favored Stevens by roughly 14 points.
A Mitchell Research & Communications poll of 406 likely voters, conducted July 28–29, 2026, showed a similar pattern, with El-Sayed leading 52% to 38%. That survey also found El-Sayed with strong support among younger voters, winning 68% of those aged 18 to 29 and 62% of those aged 30 to 44, while Stevens performed best among voters 65 and older, winning half of that group. A Zenith Research poll conducted July 26–30, 2026, similarly found El-Sayed ahead 53% to 34% on the initial ballot, growing to 59% versus 41% once undecided voters were pushed to choose.
Not every survey has told the same story. Earlier in July, a Glengariff Group and Detroit Regional Chamber poll found Stevens with a modest edge, and a Detroit News/WDIV-TV poll found Stevens leading by roughly 7 points, at 48.2% to 41.4%. These earlier results suggested a more competitive race before El-Sayed appeared to gain late momentum. Political analysts have pointed to this shift as one of the more notable developments of the summer, with some describing El-Sayed as the clear favorite going into election day, while cautioning that turnout patterns and late-deciding voters could still affect the final outcome.
Public Interest and What’s Driving the Race
Public interest in Stevens’ polling numbers has intensified partly because of what the race represents symbolically. Michigan’s Senate seat is considered one of the most competitive contests of the 2026 midterms, and whichever Democrat wins the primary will face Republican Mike Rogers, the presumptive GOP nominee, in November. Rogers narrowly lost Michigan’s 2024 Senate race and is seen by Republicans as having a strong chance to flip the seat given Michigan’s competitive political environment.
Campaign finance has also become part of the polling conversation. Reports indicate that outside groups supporting Stevens, including an AIPAC-affiliated organization, spent tens of millions of dollars on her behalf, far outpacing spending on El-Sayed’s side. Some polling on voter attitudes suggests that a notable share of Democratic primary voters may view campaign contributions tied to groups supporting Israel unfavorably, which could be a factor in how the numbers have moved. At the same time, observers note the race is not solely about that single issue, as voters have cited cost of living, healthcare, and broader questions about party direction as central themes.
Prediction markets have also drawn attention alongside traditional polling. Betting markets tracking the primary have shown El-Sayed as a heavy favorite in the days leading up to the vote, reflecting the same trend visible in the polling data. However, prediction markets and polls are not guarantees of an outcome, and Michigan primary turnout has historically been difficult to model precisely.
Latest Updates
As of primary day, August 4, 2026, polls across Michigan are open and results are beginning to be reported throughout the evening. There is no official confirmation yet of a winner, and vote counting is expected to continue over the course of the night. Both campaigns have been actively engaging supporters in the campaign’s final days, with Stevens emphasizing her record on manufacturing and cost-of-living issues, and El-Sayed holding rallies in Detroit focused on turnout among younger and more progressive voters.
Whichever candidate wins the Democratic nomination will move directly into the general election campaign against Rogers, with the race expected to remain competitive through November. Michigan’s Senate contest is widely regarded as one of a handful of races that could determine control of the chamber, adding further national significance to Tuesday’s results.
Final Thoughts
Haley Stevens polls have told a shifting story throughout the summer of 2026, moving from a competitive, single-digit race in July to a wider gap in favor of El-Sayed by the final stretch before the primary. The numbers reflect a broader divide within the Democratic Party between its establishment and progressive wings, a dynamic that has made this Michigan primary one of the most closely watched contests of the election cycle. With voting now underway, the coming hours may bring clarity on which candidate will advance to face Mike Rogers in what is expected to be a tightly contested general election battle for control of an open U.S. Senate seat.
