Yes.OK, here's an example of an ad using Trump's words against him:
Show clips of Trump with all his comments about how you can't get over his big beautiful wall juxtaposed with people climbing over and cutting through the wall.
It could end with some stats about tax dollars spent on the wall vs how effective other methods have been.
In a similar vein... Clips of Trump bragging about the tax cut helping the middle class. Then the clip of him telling the bigwigs gathered at Mar a lago how much money he made them.
