In a primary pitting two current members of the U.S. House against each other, Haley Stevens defeated fellow Democrat Andy Levin in Michigan's newly-redrawn 11th Congressional district.
The race featured a flood of outside campaign spending.
Pro-Israel groups spent millions of dollars targeting Andy Levin, who is Jewish but supports a two-state solution.
Haley Stevens rode that campaign cash cow to a chance at a third term in Congress.
But Stevens argues it was far more than unlimited funding for attack ads that wooed voters to her side.
"Certainly I believe that we need to end Citizens United. But I believe my hard work spoke for itself. Spending time in senior centers, knocking on doors in subzero temperatures, bringing people into the fold."
An offshoot of the group Emily's List — which backs women candidates who are pro-choice — also injected millions into Stevens' campaign, despite Levin supporting abortion rights as well.
