This commercial, from something called the 45Committee, also aired during the Patriots game Sunday on CBS in Boston.
Notice it doesn't say "Vote for Trump." It doesn't mention Trump. Biden, or any other candidate for office. It just says, "Tell Washington: American needs jobs, not mobs."
If for whatever reason (maybe fear of the mobs) you don't want to show up on a list of Trump campaign contributors, you can pay for an ad like this, and the level of disclosure and even scrutiny involved is minimal. As far as the calculus about whether images of the mobs help Trump or hurt him (because they took place on his watch), I guess whoever paid for this has worked it through.
