By Tim ReidWASHINGTON, Aug 4 (Reuters) – Michigan voters head to the polls on Tuesday in a high-stakes Democratic Senate primary that could shape the battle for control of Congress and the future of the Democratic Party amid a fierce internal debate over U.S. support for Israel. But, the primary is also a test of broader voter frustrations over economic concerns and the party establishment, Democratic strategists said. A Stevens win would signal she made her case despite anti-establishment headwinds, with economic concerns and the desire to beat Republicans outweighing Israel. “Either way, Democratic leaders shouldn’t ignore the anger at the status quo fueling El-Sayed’s campaign or assume a Stevens win lets the party off the hook,” Democratic strategist Karen Finney said. PROGRESSIVES AND MODERATES TAKE SIDESThe winner of the Senate primary will face former Republican Representative Mike Rogers, a vocal supporter of Israel in a state President Donald Trump narrowly won in 2024.
