The most vocal supporter of Lina Khan's work over the last few years has been JD Vance... while I can't remember a single democrat voicing even close to the same support.
JD Vance vocally supported her, then the administration he is part of fired her as soon as it was able.
By contrast, Democrats nominated her to be commissioner, officially it was Biden who did so but Elizabeth Warren, another Democrat, is the one who really pushed for it.
Words don't mean shit compared to action.
With your kind of reasoning its pretty obvious why America is currently driving itself off a cliff.
