Michigan’s closely watched Democratic Senate primary shifted after state Senator Mallory McMorrow said she is suspending her campaign about one month before the Aug. 4 primary. Her exit leaves a head-to-head contest between Abdul El-Sayed and Representative Haley Stevens for the open seat vacated by retiring Senator Gary Peters. McMorrow said in a video that she would support the eventual nominee, though she did not endorse a candidate. The remaining contenders are scheduled to debate on television this week, ahead of a general election matchup that is expected to feature former Representative Mike Rogers as the Republican nominee. Recent polling cited in the report showed El-Sayed leading Stevens, and the race has drawn national attention as a test of progressive strength in a competitive battleground state.
