Driving the news: The digital ad, “What happened to Joe Biden,” is timed to overlap with the Democratic National Convention and launches the Trump campaign’s four-day takeover of the YouTube masthead.

That’s prime internet real estate the campaign has bought in what it calls a “high seven figures” digital advertising effort to undercut the DNC’s messaging this week.

The details: The new ad splices footage of Biden speaking energetically and articulately in 2015 and 2016 alongside clips of him stumbling over his words and appearing to lose his train of thought during the 2020 campaign.

It’s the harshest president campaign attack in what is shaping up to be an even uglier messaging year than 2016.
