its hard to imagine homan is anything but a superficial pause in violence on citizens (there is the massive money funded ice momentum), but he certainly brings the trump mafia corruption bonafides.
but let's look at trump's options other than homan, who is at least in a related role and brings the rightwing media the much needed 'experience' parrot points.

1. public hardline public anti-immigration gop
(chip roy, laura loomer, etc...)
sure, since the key intent is to distract by getting someone out, and trump himself cares not for credibility. but loomer may be too going far on short notice. the others in congress that pull this stance have very cozy districts.

2. MTG ?
why not, she is not running again, and is even in the group that also wants to kill h1b for trump's megatech donors.
oh yeah, that unrelated epstein thing that is far more important to trump than immigration has ever been.

so yeah, homan seems to best for appearance of change.
