The former president's appearance is a significant show of establishment support for a progressive insurgent who survived tens of millions of dollars in outside spending to win the August primary by less than a percentage point against moderate congresswoman Haley Stevens.
El-Sayed, a doctor and former Wayne County health director, ran on Medicare for All and a refusal to take corporate PAC money. He was backed by Bernie Sanders and Alexandria Ocasio-Cortez in the primary, and made opposition to US military aid to Israel and criticism of its conduct in Gaza central to his campaign, describing Israel's actions there as genocide.
Aipac and its allies spent a record-breaking $30 million trying to defeat him, according to AP. Stevens and her allies collectively outspent El-Sayed's side nearly nine to one on advertising, per AdImpact. Stevens, backed by Senate Democratic leader Chuck Schumer, incumbent senator Gary Peters and the party establishment, won Wayne County overall with about 51% of the vote to El-Sayed's 45%.
Obama's presence matters most in Detroit, which is more than three-quarters Black and where he remains highly popular. During the primary, some ads backing Stevens used old footage of Obama praising her, which critics called misleading because he had not endorsed in the race. Kamala Harris campaigned with El-Sayed last month, and Obama phoned him after the primary.
El-Sayed faces Republican former congressman Mike Rogers for the seat vacated by retiring Democrat Peters. The contest is one of a handful that will determine Senate control next year. Rogers was the Republican nominee in 2024 but lost that race despite Donald Trump winning the state. A Marist poll of registered voters from late September had El-Sayed ahead 51% to 44%.
