Past research ([1]) has shown that Twitter disproportionately boosts right-wing political content. Qualitatively, you can find whatever you want there, but Elon Musk's personal connection with and admiration for a number of right-wing individuals makes them stand out. In particular, Twitter under Musk has a clear pattern of not applying its moderation policies to high-profile accounts; in the current year, it is right-wing politicians who most frequently post hateful or blatantly false information, so failing to hold them to a normal standard amounts to a tacit approval of what they're posting.
