With covid numbers falling from the inevitable January spike after the holidays, lifting omicron restrictions was always going to happen sometime this spring. (Barring some new deadly hypothetical variant.)
But I don't doubt that both parties factor PR into all of their decisions, down to how they dress.
The implication that a PR firm could dictate that the country would remain shut down until November despite covid numbers this low is silly. But I'm sure timing and messaging and other details are informed by PR studies.
Whether from fear of losing their jobs or wanting to carry out the will of their constituents, lawmakers have to pay attention to what we think either way.
