Joe Biden, one of 24 candidates for the Democratic presidential nomination, has promised that if elected president, “We’re gonna cure cancer.”

“I’ve worked so hard in my career, that I promise you, if I’m elected president you’re gonna see a single most important thing that changes America—we’re gonna cure cancer,” said Biden.

What could easily be considered a tall campaign promise garnering eye-rolls, was met with applause at an Ottumwa, Iowa, campaign rally.

Former Vice President Joe Biden lost his son Beau Biden, the former attorney general for the state of Delaware, to brain cancer in 2015. Beau was 46.

So, it might be hard to begrudge Biden for making a promise that a politician cannot reasonably make happen.

Recent flip flop

What some supporters are begrudging him for is his apparent change of heart, as he is now opposing the federal Hyde Amendment that prohibited taxpayer dollars for most abortions.

It was only last week, June 5, that his campaign reaffirmed his position for the Hyde Amendment, and then he changed his position the next day.

After the Iowa rally, Biden denied the change was for political gain. Speaking to WHO-TV he said the majority of Americans agree with the Hyde Amendment, “So the idea that this would be helpful to change is not accurate in terms of being able to win an election.”

The Hyde Amendment was originally passed in 1976, three years after abortion was legalized, but took effect in 1980, according to the American Center for Law and Justice.

The American Center states the amendment has had bipartisan support in Congress and widespread consensus as a sound and important policy during the post-Roe v Wade era for more than 40 years.
