She met Huey Long after she won a cake-baking contest that he had organized to promote a product that he was selling at the time.

After Huey's assassination in 1935, in an example of widow's succession, Rose was appointed to serve in his seat in the United States Senate until a special election could be held.

She was also survived by her sons, Palmer Reid Long of Shreveport, Louisiana, and Russell B.

On February 1, 2014, Mrs. Long was posthumously inducted into the Louisiana Political Museum and Hall of Fame in Winnfield.
