Donald Trump and Joe Biden will be the only two candidates participating in next week’s CNN presidential debate, the network said, as independent Robert Kennedy Jr. failed to qualify. To qualify, candidates had to be on enough state ballots to reach 270 electoral votes, or enough to win. They also had to receive at least 15% in four separate national polls, among those specified by the network. Jake Tapper and Dana Bash will moderate the June 27 debate from CNN’s Atlanta studios.
