Cynthia is the president of a political media firm. For her role as a media producer in the hotly contested Michigan Senate race that elected Mrs. Stabenow, she was called a rising star of political media.
I wonder if you could suggest something for the bolded part.
I have come up with:
...en las sumamente reñidas elecciones para el Senado de Michigan
...en la reñida elección...
No sé, alguna sugerencia??
