A possible October surprise is looming that could propel Kamala Harris over the finish line – an increasingly out of it Joe Biden resigning and handing the reins of power to the Democratic nominee weeks before the Election.

Amid renewed questions about whether Biden is fit mentally and physically to stay in office, Harris takes over and gets a final boost from the glow of making history and becoming president.

The scenario would be enough to tilt the close race in Harris’s favor over a frustrated Donald Trump.

Could it happen?

Some Democrats are quietly rooting for it, and there are signs that even Biden may not last out his term.

Over the weekend, a clearly disengaged Biden – who has become virtually invisible anyway – forgot what he was supposed to do at a meeting of four world leaders including Indian Prime Minister Narendra Modi in Wilmington, Delaware.

“Thank you all for being here and now, uh, who am I introducing next?” the 81-year-old Biden asked the crowd.

After a lengthy silence, Biden began snapping – apparently at his staff – “Who’s next?” before Modi finally walked on stage.

It was just the latest of many embarrassing episodes where a forgetful Biden didn’t know what he was doing.

The day before, Biden let his wife Jill run a Cabinet meeting in the West Wing while the president stared off into the distance as Jill talked about women’s health research for four minutes. And that night Jill Biden took over the White House for a party for the cast of the West Wing.

The October surprise scenario does carry some risk, though. If Harris takes over she assumes all responsibility for everything that goes wrong, including the potential of the Israel-Hamas war expanding into a major war in the Mideast region. The Pentagon announced Monday that the U.S. was sending more troops to the region.

That could expose Harris’s relative inexperience in foreign affairs.

If Harris becomes president, she would also have to face media questions and not just ignore them like she does now.

From a first glance, you wouldn’t think Harris would need the boost of becoming president to win the election. National polls show her holding a small lead and the left wing media follows in tow, putting a shine on Harris’s every move.

But the national vote means nothing. The electoral map favors Trump. If he wins Pennsylvania and two southern states, North Carolina and Georgia, he takes the election.

Some leading unions have also given boosts to Trump and his attempt to win over blue collar voters. The Teamsters non-endorsement of Harris is a major snub for Democrats, and Teamsters head Sean O’Brien’s recent comments that a clear majority of rank and file union members favor Trump is troubling.

“It’s unfortunate because I’m a Democrat and coming from a state like Massachusetts, but it adds credibility to what we’ve been saying all along, the Democratic Party has taken the working men and women for granted,” he told the Boston Globe.

Harris does have union support, like the one representing IRS workers – but that plays into Trump’s claim that she will increase the number of IRS auditors.

Another blow for Harris recently was Hamtramck, Michigan Mayor Ameer Ghalib’s endorsement of Trump. The Arab American mayor, whose city has an all-Muslim city council, called Trump the “right choice for this critical time” and a “man of principles.”

Ghalib’s endorsement could hold weight in the swing state of Michigan, which has a large population of Arab American voters.
