Joe Biden's mental decline has become the talk of the nation, but he can still count on the support of millions of Americans desperate to keep Donald Trump out of the White House.

Democratic voters at a Kamala Harris campaign rally told the Daily Mail that they would vote for Biden if he was in a nursing home, with one woman saying Biden's debate performance reminded her of her own mother's last days of life. 

Dems support Biden NO MATTER WHAT?

Biden's performance has caused ongoing panic in the Democratic party and handwringing over whether he should be replaced, at the last minute, with a more capable nominee.

While Democrats are deeply divided about where to go next, they are united by the common goal of defeating Donald Trump no matter what it takes.

For many Democrats, that means resigning themselves to voting for whoever the Democrats nominate - even a corpse, as long as "D" is next to the name. "It's an administration, not a president" is the cynical sentiment sweeping the party.

Retired minister Mark Lukens, 68, speculated that it's "too late" to swap Biden out but he said he would vote for Biden in any circumstance.

"We'll support whoever they come up with. But at this point in time, I think I'd go with Joe Biden if he was phoning it in from a nursing home," he said.

Biden struggles to calm nerves

Another voter told the Mail that Biden's feeble debate performance reminded her of her late mother's health decline.

"He reminded me of my mother five years before she passed away," Kat, 67, said. "She passed away at the end of this past September and he reminded me of her for about five years before she passed away. He's on that downward trend, you know?"

Biden's vulnerability has prompted speculation about changing candidates, with many looking to his vice president., Kamala Harris, as a natural pick.

"I feel like she could run the country in the unfortunate event there's any reason that he would need to step down," Vivienne Bailey-Reid, 61, told the Mail.

While Biden has responded to pressure to step aside with defiance, he has failed to reassure rattled members of his own party that he is up for the job.

Biden's aides met with Senate Democrats on Thursday for another attempt at calming nerves, but Democrats left the meeting as concerned as before.
