Vice President Kamala Harris has quickly emerged as the Democratic Party's presumptive presidential nominee after Joe Biden dropped out of the race on Sunday and endorsed her, drawing support from other leading figures in the party.

The question remains, however: who will be her running mate?

Choosing a candidate is a delicate matter, with several factors to consider, such as winning key states, winning votes in rural areas, attracting moderates, or catering to different demographics.

The selection process, which normally takes several months, is being accelerated this time so that the final results can be announced during the Democratic National Convention, which begins on August 19 in Chicago.
