But I think is also a really good example of how Donald Trump is a really terrible advocate for any political cause he associates himself with.
Americans, largely, have fallen more in the right-spectrum on border related issues, both during his Presidency and since. But during his time in office at least, he made choices on how to pursue those issues and, by extension, that hindered his ability to get anything done.
Put another way, at some level, he has to be held responsible for how he framed/frames his rhetoric on border issues.... sure, the sound-biting is what it is and lacks nuance, but given how incendiary his rhetoric often was/is, he often reinforces the sound-bites as well.
