The current case numbers come with a lower fatality rate so the same case numbers don't suggest the same level of action as before.
Also the context of the numbers matters. They're trending down now, not up, and the variant spikes are over. In the middle of delta/omicron we didn't know what was going to happen.
And yes, there's fatigue on everyone's part. The relative lower danger of omicron, plus being past the delta spike then the omicron spike, means we're just kind of collectively over it. Citizens have fatigue, they're just not built to stay on guard for a third year. Policy makers are fatigued, they can't force people to stay home for another year to save lives from covid just like they can't force people to stop driving to save lives from car crashes.
So admitting there's a political aspect is fine, but it's a lot more nuanced than the election cycle, which is a much more contrived explanation than everyone's response to a dramatic drop in the numbers.
