Biden is outspending Trump on TV in most or all of the swing states. The Trump campaign, in all likelihood, is not worried. After all, Trump was outspent in 2016, and he can count on all sorts of free media coverage that isn’t available to Biden. He can dominate the airwaves without spending a dime.
That’s a two-edged sword, however. Trump isn’t capable of making a case for himself with swing voters when he’s unscripted. Every time he appears on the evening news, he helps Biden, not himself.
