An estimated 43.15 million viewers tuned in to the CBS News vice presidential debate this year, according to Nielsen, a media analytics company. The debate was held at the CBS Broadcast Center in New York City, and aired across more than a dozen stations.

Four years ago, 57 million tuned in to the only vice presidential debate of the 2020 election cycle between Harris and then-Vice President Mike Pence. In 2008, a record 69.9 million watched Joe Biden and Sarah Palin face off on television in the most-watched VP debate, according to Nielsen.

On Tuesday, Sen. JD Vance (R-Ohio) and Minnesota Gov. Tim Walz (D) faced off in a vice-presidential debate for what could be the last time that Americans hear from either presidential ticket on the debate stage before Election Day.
