Could Barack Obama run for president in 2020?
Oh, I didn't know that. Do you think it's possible for someone else to take his place in the Democratic primaries?
Yes, it's certainly possible for someone else to enter the race for the Democratic nomination. Many candidates have already announced their campaigns, and more may join in the coming months. It will be up to the voters to decide who ultimately wins the nomination.
