Democrats are quickly coalescing behind Senate nominee Abdul El-Sayed after the far-left candidate narrowly clinched victory in Michigan’s Democratic primary on Wednesday morning, while Republicans quickly pounced on El-Sayed’s extremist history and ties.

Rep. Haley Stevens (D-MI), who came within a percentage point of defeating El-Sayed, promptly congratulated him on his victory and offered her support.

“I want to congratulate Abdul El-Sayed on winning the Democratic nomination for U.S. Senate. He is a doctor, a community health official, a Rhodes Scholar, and a dedicated Michigander. I am proud to offer my support as he takes on Mike Rogers in the general election,” Stevens said. “This was a thorough and rigorous campaign that brought out the full span of views within the Democratic Party — and that is why we have primaries.”

She emphasized the need for Democrats to come together in support of El-Sayed, saying, “We must elect Democrats up and down the ballot. We need to flip some important House seats. We need to re-elect my friends Hillary Scholten and Kristen McDonald Rivet. We need to win this Senate seat, because Elissa Slotkin deserves a partner like Abdul in the U.S. Senate.”

Senate Minority Leader Chuck Schumer (D-NY) and Democratic Senatorial Campaign Committee Chair Sen. Kirsten Gillibrand (D-NY) also offered support for El-Sayed in a statement.

“Abdul El-Sayed has run an energetic campaign that inspired thousands of Michiganders across the state, with a clear focus on lowering costs and standing up for working families,” the pair said. “Democrats are united by a common purpose: putting a check on Donald Trump by defeating his Republican enablers and taking back the Senate. We look forward to working with Abdul and Democrats across Michigan to win this seat in November.”

Sen. Elissa Slotkin (D-MI), who declined to endorse El-Sayed in the primary, offered her support while saying little about El-Sayed personally and focusing on the need to keep the seat in Democratic hands.

“Congratulations to @AbdulElSayed for winning the Democratic nomination for Senate. It’s been a long primary, but now it’s time to gear up to beat Mike Rogers (again) and win up and down the ticket,” Slotkin said. “There is nothing more important than the mission of the next 90 days: uniting, keeping this seat blue, flipping the House and Senate, and providing a real check on President Trump.”

Meanwhile, Republicans have quickly pounced on El-Sayed, highlighting his extreme history.

“Abdul isn’t just another liberal. He’s an extremist. He wants to empty prisons and put murderers and sex offenders back on our streets. He pledged his support to the Muslim Brotherhood and campaigns with people who refuse to condemn terrorism,” Republican nominee former Rep. Mike Rogers (R-MI) said. “I spent years hunting terrorists and bringing Osama bin Laden to justice. Never in a million years did I think that I would be running against someone who believes America deserved 9/11.” His comment was apparently a reference to El-Sayed’s ties to far-left streamer Hasan Piker, who championed El-Sayed in the primary.

Matt Brooks, CEO of the Republican Jewish Coalition, declared in a statement that El-Sayed is the “most antisemitic U.S. Senate candidate in America” and called on Jewish Democrats, who he said could prove “decisive” in the November general election, to back Rogers.

“Abdul El-Sayed is a direct threat to Michigan’s Jewish community,” Brooks said. “El-Sayed has called the government of the Jewish state as ‘evil’ as Hamas, ‘struggled’ to say that Israel has a right to exist as a Jewish state, and empathized with a terrorist who tried to murder Jewish schoolchildren at Temple Israel in the Detroit suburbs — and yet, Michigan Democrats just picked him as their nominee for the United States Senate.”

The Senate Leadership Fund, a super PAC aligned with Senate GOP leadership, announced a six-figure digital ad campaign describing El-Sayed as “dangerous.”
