The campaigns for President Donald Trump and Joe Biden spent a combined $192.3 million on Facebook advertising in the first 10 months of 2020, with over a quarter of that coming in October alone, according to data from Facebook Inc.

The presidential campaigns for each party more than doubled their ad spending on the social network compared with the presidential candidates in the 2016 race, when experts agreed that Trump outmaneuvered Democratic nominee Hillary Clinton online.

Biden spent slightly more on Facebook than Trump this year, at $99.8 million compared with $92.5 million, though the president poured more into Alphabet Inc.’s Google, where the two campaigns have spent a combined $215.5 million on ads on Google since May 2018. That spending came largely on YouTube, including a wave of Trump ads on the video site’s homepage this week.
