I think it's complicated. We didn't really have a "Federal" solution under Trump. Then Biden runs on a campaign to provide a "Federal" solution. As Rama pointed out, it's hard to have a Federal solution when the States are all over the place. So Biden, on a call to the "States" says, You guys need to fix this, we can't because of you guys...
A change in course, for sure. But every course has changed. Delta smacked us silly and Omicron will be a transmissibility war. The States, take DeSantis as an example, have been defying Feds, clamoring for decision making in their own fiefdoms. One would think the GOP Govs would reward this notion. It's what a lot have been begging for all along. States rights, baby! That's a GOP mantra.
