But these may be bot followers. In terms of actual human engagement, I see a definite right-wing bias. It seems like the stuff that goes viral and is algothrimically- recommended on Twitter leans right or center-right.
That may be partially due to the promotion of the blueticks, who seem to be predominantly, well, either crypto scammers or weird Musk fans.
Sampling error is huge in this.
Surveys of newspaper editorial policy are notoriously subjective, the Glasgow media group got pasted for an overt Marxist analysis during the thatcher years, ignoring what ground truths it exposed because of perceptions of bias in their intent and they were quite rigorous and peer reviewed.
