The voices on this particular video are all conservative because it's a clip from the Daily Show, not an unbiased sample, and of course they're going to mainly pick on the other side. People on the right are making similar lists of grievances against left-wing media, and if you looked exclusively at those, you'd get the impression that downplaying the coronavirus is a liberal thing.

(My own pet interpretation is that political news reporting is a circus, reality-adjacent at best, and most journalists leave you worse-informed for having listened to them regardless of their party affiliation.)
