NEW REMAKE OF MEAN GIRLS NOT READY FOR PRIME TIME: Jill Biden’s grudge against Kamala Harris REVEALED: Power-hungry first lady’s grudge is so deep that the only thing worse than Joe stepping down is the VP replacing him.

When Kamala Harris took to the stage during a Democratic primary debate before the 2020 election and implied that Joe Biden was racist, his wife, Jill’s, response was crystal clear.

‘Go f**k yourself,’ the then-future first lady vented, as she allegedly admitted during a conference call with supporters.

And the relationship between the two women – that began badly enough during that contentious battle for the presidential nomination – has only gone downhill from there.

Now, political insiders have told DailyMail.com that Democratic advisors are struggling to push past the powerful role that Jill Biden‘s loathing of Harris, 59, is playing in Joe‘s resistance to pass the mantle to his VP as pressure ratchets up for him to step down as presidential candidate and allow another Democrat tackle Donald Trump.

According to one former Democrat operative in Jill’s circle, the women’s long-seated animosity is ‘one hundred per cent’ part of Jill’s resistance to having her 81-year-old husband step aside.

Because the truth, according to a source who knows the First Couple well, is that Jill’s is now the only voice to which the 46th president listens.

And as far as Jill, 73, is concerned, the only thing worse than her husband stepping down would be Kamala stepping up to replace him.

To be fair, she’s far from the only person thinking that right now. But didn’t anybody in Team Biden wargame how this would play out, particularly when Biden was still feigning that he would be a one-term president?

Speaking of which, as Jim Geraghty asks: What If Kamala Harris Genuinely Doesn’t Want to Be the 2024 Nominee?

What if she can read a poll as well as anyone else, and thinks that there’s a good chance she would lose to Trump? If Biden loses to Trump in November, her reputation is intact — she did all she could, but the ticket couldn’t overcome the liabilities of an octogenarian nominee who bombed (at least) the first debate.

But if in November, Kamala Harris lost to Trump — after January 6, after Trump’s indictments, after Trump’s convictions — her reputation would be ruined, and she would never be the Democratic nominee again.

And if Harris lost to Trump in 2024, after Hillary Clinton lost in 2016, would that mean that Democrats would be hesitant to nominate another woman for a long time to come?

For Democrats, the consequences of a Trump victory over Biden are dire. But the consequences of a Trump victory over Harris are even more catastrophic. If Biden can hang on, hold onto to the “blue wall” states, and hold on against a famously erratic Republican who has demonstrated he has a hard ceiling of support, Democrats are home free. Harris can take over on the afternoon of January 20, 2025, if the Bidens are amenable.

Stay tuned.
