How to Watch the Biden-Trump Presidential Debate

The moment has been four years in the making: President Biden and former President Donald J. Trump on a debate stage, another flashpoint in their long-running hostilities.

The debate, hosted by CNN at its Atlanta studios starting at 9 p.m. Eastern time on Thursday, will occur without an in-person audience and before Mr. Trump and Mr. Biden formally accept their parties’ nominations this summer, in a dramatic departure from the past.

No. He failed to meet CNN’s requirements, which means Ross Perot remains the last independent candidate to have qualified for a general election presidential debate — and that was in 1992. For this debate, participants had to receive at least 15 percent support in four approved national polls and qualify for the ballot in enough states to have the chance to earn the 270 electoral votes needed to win the presidency.

The moderators will be Jake Tapper and Dana Bash, who are fixtures on the anchor desk at CNN and the hosts of the network’s Sunday political talk show, “State of the Union.” Mr. Tapper is CNN’s chief Washington correspondent, and Ms. Bash is the network’s chief political correspondent.
