This incident, alone, should become something that could be used against them. Run it as a loop, then have a voiceover ask, “Would you trust them to be able to take care of your children?” “I’m Donald Trump, and I approve this message.” They would be forced to explain themselves!
It would be good if more people saw that clip, but it shouldn’t come from Trump or Trump’s campaign, because I can guarantee what would happen if such a commercial came from his campaign. He’d be attacked for “dragging Walz’s family” into the campaign, politicizing his son, etc. So Trump should personally steer clear. But as far as pro-Trump organizations, individuals or SuperPACs bringing it up? Most definitely.
