There’s no way on Earth to overstate the importance of Joe Biden’s pending decision on who to select as a vice-presidential running mate in his campaign against Donald John Trump and Mike Pence.

When given the opportunity to speak of Biden, former President Barack Obama says often that his selection of Biden as VP in 2008 was the “best decision” he ever made as president.

So it will be for the Democrats’ presumptive presidential nominee in 2020.

Biden has pledged to select a woman to run with him. That wipes out roughly 50 percent of all the qualified individuals from whom he can select. The remaining field of VP candidates, though, is a rich one indeed.

Here is where it might get a bit sticky for the former vice president: He has this crisis involving the death of an African-American man at the hands of police officers who roughed him up, then suffocated him on a Minneapolis street. There is pressure building on Biden to select an African-American woman to run with him.

Make no mistake at all, the field — even if Biden is narrowing his choices even more — remains packed with talent, with accomplished individuals who have stellar public service records.

I will not get into trying to name the possible VP candidates Biden should consider. I would forget someone. I won’t go there.

However, it is no small task facing the former vice president — who President Obama has called the “best vice president we’ve ever had.” Whether he is the best ever or whether Obama was just saying so to brag about his executive appointment skills, what matters now is whether Joe Biden can find someone who will enhance his chances of defeating Donald Trump.

More critically, though, he must find someone who is able to serve as president of the United States. I mean, let’s stare reality in the face: Biden will be 78 years of age in November of this year; he has suffered some potentially serious health issues in the past.

Joe Biden has to hit this pitch out of the park.
