Former Vice President Joe Biden continued his gaffe-riddled campaign tour this week; telling an audience the assassinations of Martin Luther King Jr. and Sen. Robert Kennedy took place in the “Late ‘70s.”

“Just like in my generation, when I got out of school, when Bobby Kennedy and Dr. King had been assassinated in the ’70s, the late ’70s when I got engaged … ,” Biden recalled.

The two leaders were killed two months apart in 1968.

Biden is facing more campaign issues this week; with analysts saying his fundraising efforts have “tumbled” since a series of gaffes on the campaign trail.

“Joe Biden raised $4.6 million online on his first day in the 2020 presidential race, surprising doubters who thought the former vice president couldn’t run a modern campaign. But since then Biden’s online fundraising has tumbled — looking more like flash-in-the-pan opponent Beto O’Rourke than top-tier rivals like Bernie Sanders or Elizabeth Warren,” reports Politico.

“More than 60 percent of the $13.2 million Biden has raised online came in the first week of his campaign, which launched in late April, according to a POLITICO analysis of data from the Democratic fundraising platform ActBlue. While other top candidates spiked early and then gradually raised more money online as the 2020 campaign has carried on, Biden’s pattern is similar to O’Rourke, who roared into the race with millions raised in his first day but has trickled off since then,” adds the website.

Democratic strategist David Axelrod weighed-in Thursday on Joe Biden’s potentially reduced campaign schedule; saying “this is bad advice” and claiming the former Vice President can “either cut it or he can’t.”

“This is bad advice. You can’t cloister the candidate and win. He either can cut it or he can’t, and the only way he can prove he can is to be an active and vigorous candidate. He’s running for president of the United States, for God’s sake!” posted Axelrod on social media.

Allies and political insiders close to Joe Biden are reportedly telling the former Vice President to scale back his campaign stops and speaking events; hoping the reduced schedule will minimize future speaking gaffes.
