Wow.

This election race has become infamous for surprises but nothing surely quite to rival today’s FBI bombshell about Hillary Clinton’s email server?

Just when it seemed like Donald Trump’s presidential hopes were dead and buried, along comes a game-changing October Surprise of epic, possibly result-influencing proportions.

FBI director James Comey’s astonishing revelation that NEW ‘pertinent’ emails have been found on a NEW electronic device, weeks after the investigation into Hillary’s email usage ended with no charges is bad enough.

Even worse for her is that the device was uncovered during a separate FBI investigation into Anthony Weiner’s sexting of an underage girl, revealed by DailyMail.com.

Just as Hillary was beginning to plan what curtains to put in the Oval Office, her campaign has been engulfed by a new tidal wave of sleazy headlines in every form

Emails were found on a device used by Clinton's top aide Huma and her estranged husband Anthony Weiner thanks to an investigation into his lurid, underage sexting scandal

Weiner, of course, is the estranged husband of Clinton’s No1 aide Huma Abedin. The device belongs to either him or her.

It doesn’t get much closer to the candidate than this.

So at the precise moment Hillary was beginning to plan what curtains to put in the Oval Office, her campaign has been engulfed by a new tidal wave of sleazy headlines in every form.

It couldn’t be more horrific timing for Clinton given there are just 11 days to the election, because it plays straight to Trump’s central campaign narrative of ‘Crooked Hillary’.

She can’t be trusted, he told us.

Her use of a private email server was a criminal scandal, he insisted.

The FBI decision to clear her of any wrongdoing was a fix, he raged.

The whole damn system is rigged, he roared.

Now, Trump’s Christmas has come early.

Trump’s Christmas has come early with this. The whole damn system is rigged, he roared at campaign events on Friday afternoon

Hillary was one of the last to hear about the bombshell because she - along with Huma, pictured today before the news broke, was on her plane with, irony of all ironies, no Wi-Fi

In fact, given he hates Weiner even more than he hates Hillary, you could make that 10 Christmases coming at once.

It’s an extraordinary, unprecedented situation and it’s very hard to predict what will happen next.

Hillary herself was one of the last to hear about the development when it blew up because she was on her plane with, irony of all ironies, no Wi-Fi.

By the time she walked off, with a forced smile and distinct slump to her shoulders, she will have calculated just how big a deal this is and what a massive problem it may prove to be.

Hence the furious response from her campaign chief John Podesta demanding that Comey explain his actions.

I can’t say I’m as surprised as many others that the email scandal has come back to haunt her.

A year ago, I wrote a column for DailyMail.com after yet another series of email-related revelations erupted, that was headlined: ‘Stick a fork in her because Hillary’s done. Nobody will ever trust her again.’

I said then: ‘The email scandal that engulfed her several months ago is still raging as ferociously as it was, in fact more so. It won’t go away because it stinks to high heaven and nobody believes almost anything she’s said about it.’

I added: ‘The more Hillary has protested her innocence, the more guilty she’s looked…. This is a woman who promised ‘transparency’ but has delivered the complete opposite. She looks like every other dodgy politician in Washington.’

Then I concluded: ‘Hillary’s private email server has become her personal Nemesis. It will drag on and on and on, dragging her further down with each new revelation.’

It's not an exaggeration to say this could cost her her the presidency. Her slumped body language showed it. And I predicted it 13 months ago

Well here we are 13 months later, a week before the election, and the scandal has reached dramatic new heights.

We don’t know yet what these emails say, who wrote them, or how damning they might be, but we do know they must be materially significant to the original investigation because it defies belief that Comey would have pulled this trigger if they’re not.

It’s very possible we may not know the crucial answers until after the election, which might be the worst-case scenario for Clinton because it will simply allow Trump to pound away until November 8 without any concern about her being exonerated again before it’s too late.

What this bombshell will indisputably do is galvanise Trump, rally his base, deflate Clinton’s, and almost certainly influence some independents.

This bombshell will indisputably galvanise Trump, rally his base, deflate Clinton’s, and almost certainly influence some independents. Momentum has shifted

So it’s not a wild exaggeration to say it could actually cost her the presidency, fear of which caused stock markets to instantly tank on the breaking news and betting odds on a Trump victory being suddenly slashed.

If it does, then Hillary only has herself to blame.

She has not been transparent about this email business from the start and everyone knows it, even her own staff as illustrated by the Wikileaks revelations we’ve been reading over the past few days.

The big question is why?

Perhaps these new emails will give us the answer.

Perhaps they won’t.
