The Democratic National Convention is exactly one week away and presumptive Democratic presidential nominee Joe Biden has yet to select his running mate -- leaving supporters, detractors and the contenders themselves anxiously waiting for his announcement.

The presumptive nominee has played his cards close to the vest in recent months, holding a number of fundraising events with a host of potential contenders but seldom addressing the decision in public. Biden told reporters during a rare news conference at the beginning of July that he had prepared a list of “women of color” for consideration – but he wouldn’t announce a decision until August.

“There are a number of women of color. There are Latino women. There are Asian. There are — across the board. And we’re just underway now in the hard vet of going into the deep background checks that take anywhere from six to eight weeks to be done,” Biden said.

JOE BIDEN SHOULD NOT DEBATE PRESIDENT TRUMP, CLINTON'S EX-WH SPOKESMAN SAYS

And in recent days speculation has heated up even more, leading Biden himself to quip to about the media's enthusiasm to cover a vice-presidential selection. A reporter asked Biden if he'd made his choice, according to the Washington Post, and Biden responded: "Are you ready?" He also quipped to Fox News on Saturday that he's decided, only to claim his pick was a Fox News reporter -- with his campaign later saying Biden was clearly joking.

Here's a handy guide to Joe Biden's potential running mate options.

Sen. Kamala Harris, D-Calif.: Harris has long been considered a frontrunner in the VP race, but her record as a prosecutor and contentious debate exchanges with Biden during the primary are seen as liabilities. Kamala Harris: 5 things to know about Biden's possible Democratic VP contender

Rep. Val Demings, D-Fla.: Demings was the first female police chief in Orlando, Fla., and her husband was the city's first Black police chief. She saw her national profile increase as one of the House's impeachment managers earlier this year, but her past as a cop could hurt her at a time when law enforcement is not popular with some in the Democratic Party. Val Demings: 5 things to know about Biden's possible Democratic VP contender
