With the FBI now investigating Hillary Clinton's email shenanigans, Vice President Biden -- 72 years old -- is now ramping up to challenge her for the Democratic presidential nomination.

How do we know this?

First, Mr. Biden met with President Obama yesterday and it leaked out that the president has no problem with old Joe making the run.

In fact, Mr. Obama has sent a very public signal:

WHITE HOUSE PRESS SECRETARY JOSH EARNEST: “The president does plan to vote in the Illinois primary and that ultimately it will be Democratic voters who are responsible for choosing the Democratic nominee. ((EDIT)) I wouldn't rule out the possibility of -- of an endorsement of the Democratic primary.”

That's big, as President Obama's standing in the Democratic Party is immense.

The president and the vice president are close personal friends.  It is almost inconceivable that Mr. Obama would not endorse Joe Biden over Hillary Clinton, with whom he has a distant relationship.

Also, Mr. Biden has been meeting with advisors and money men in addition to Democratic stalwarts like Senator Elizabeth Warren.

If he does run, Biden will have to announce soon.

Talking Points believes he will be in the race.

That being said, once he does commit he will be hammered.

And there's plenty of ammunition.

BIDEN (2006): “In Delaware, the largest growth in population is Indian-Americans moving from India. You cannot go to a 7-11 or a Dunkin Donuts unless you have a slight Indian accent.  I'm not joking.”

((EDIT))

BIDEN (2012): “Romney wants to let the -- he said in the first hundred days he's going to let the big banks once again write their own rules, 'unchain Wall Street.'  They're going to put y'all back in chains.”

((EDIT))

BIDEN (2010): “I am very optimistic about -- about Iraq. I mean, this could be one of the great achievements of this administration.” 

Wrong.  As we all know, Iraq is one of the great disasters of the Obama administration.

However, to be fair all politicians, pundits and American citizens have said dopey things. All of us are guilty of that.

Now as far as Hillary Clinton is concerned, things may get even worse.

The email evidence made public so far is pretty much enough to indict her on a misdemeanor national security beef.

If the FBI discovers she had her e-mail server professionally scrubbed, then the former secretary of state could be looking at a felony charge.

Bottom line, any charges against Hillary Clinton will take her out of the race and Joe Biden knows it.

So we have high drama.

And the presidential race is just getting started.

That's the memo.
