It's just good rhetoric. Many people voted for trump because they somehow thought he'd make things more affordable for them. Pointing out that he's doing the opposite is good. It also gives self-interested people a reason to care about immigrations issues.
From experience, these morons will find a way to blame it on Biden. I have zero hope for Trump voters getting out of their delusions because they are in a social media induced feedback loop. There is going to be so much pain in the next 4 years
