Story highlights 89-year-old Gertrude remembers the Nazi era in Vienna

In heartfelt video, she says Freedom Party talk of civil war made her shiver

(CNN) An 89-year-old woman who was the only member of her family to survive the Holocaust sent a heartfelt plea to young people not to let the far-right candidate win Austria's presidential election.

A video of Gertrude -- she didn't give her last name -- has gone viral with more than 3 million views since it was posted online last Friday, a little more than a week ahead of the December 4 re-run vote.

"It's probably my last election," said the retiree from Vienna.

"There's not much future for me. But the young have all their lives ahead of them and it's up to them to see that they continue to do well. They can only do that if they vote wisely."
