MINNEAPOLIS — Eleanor Mondale, the vivacious daughter of former Vice President Walter Mondale who carved out her own reputation as an entertainment reporter and radio show host, has died at her home in Minnesota. She was 51.

Family spokeswoman Lynda Pedersen said Mondale died Saturday. She had been diagnosed with brain cancer years earlier.

Mondale had been off the air at WCCO-AM in Minneapolis since March 19, 2009, when she announced that her brain cancer had returned a second time.

Mondale, the middle of three children born to Walter and Joan Mondale, stumped for her father in his failed campaign to unseat President Ronald Reagan in 1984. She also made calls in 2002 in her father’s last campaign, when the former vice president took the ballot slot of Sen. Paul Wellstone, who died in a plane crash just days before the election.
