As The New York Times reported, Bush Ellis was known for holding political views uncommon among members of her family. Unlike her brother, elected as president in 1989, and nephew, elected as president in 2000, Bush Ellis was a "liberal Democrat," according to the Times.

She was a known environmental activist, according to the Times. She also supported other left-leaning causes and organizations, including the NAACP, where she once served as the head of the NAACP Legal Defense and Educational Fund for the organization's New England chapter, according to the report.

Her brother, the 41st US president, died in November 2018, also at the age of 94. Former first lady Barbara Bush died at the age of 92 in April 2018, just several months before her husband.

Despite their conflicting political views, Ellis campaigned for both her brother and her nephew during their respective runs for the Oval Office, the Times reported.
