Mallory McMorrow dropped out of the Democratic primary for Michigan’s U.S. Senate seat on Sunday, drawing the field down to two candidates.

McMorrow, a state senator, released a video stating that she would be suspending her campaign, with one month to go before the August 4 primary. Her two opponents in the race, Rep. Haley Stevens and Abdul El-Sayed, released statements thanking her for running a hard-fought campaign for the seat.

Polls throughout the winter and spring showed the race a competitive three-way split between McMorrow and her two rivals, who all picked up powerful backers in Washington. Backing the state senator were three sitting members of the Senate, Elizabeth Warren, Chris Murphy and Martin Heinrich. But multiple consecutive surveys over the summer showed her support evaporating.
