President Joe Biden is planning to attack former President Donald Trump’s character as part of his reelection strategy. Biden may be one of the worst possible messengers for that.

The Biden campaign is spending $50 million on an called “Character Matters,” with the campaign describing it as the “central dynamic of the race” that Trump “only cares about himself.” The ad will focus on the political prosecution of Trump for paying hush money to a porn star, using a Democratic district attorney’s political use of the justice system to label Trump as a felon.
