Don’t do it, Stacey Abrams. It’s a terrible idea.

Now that it appears all but inevitable that Joe Biden will enter the 2020 presidential race, he is reported to be considering announcing at the outset that he has already selected the former Georgia House minority leader to be his running mate.

Axios’s Mike Allen, who broke the story Thursday, quoted a source close to Biden as saying the dramatic pick of an African American woman who is a rising star in the Democratic Party would show that the former vice president "isn’t just another old white guy."

If she joins Biden’s ticket, of course, there is always the possibility that she could make history in an even bigger way. But the gimmick is so transparent that it also carries the real risk of devaluing her own political brand.

What’s more, Abrams would spend the next year or more acting as Biden’s human shield, constantly called upon to answer for his past positions on issues that put him at odds with African American and female voters.
