Right now, their "declining" support is based solely on the Epstein files. Which means that they'll continue to support fascists as soon as Rogan, Peterson, etc al, can convince them that the Epstein files have been released and were never that interesting, or that maybe we'll never see the Epstein files but that's old news and something else is way more important now.
My bet is on the latter, since that's just a matter of less time spent talking about the Epstein files and more time spent talking about [distraction].
