The article does not present the Republicans' intentional obstruction US efforts to protect Americans from Covid. (It is hidden behind the word "polarized", which creates a false equivalence between Republicans and non-Republicans.)
Their obstruction started in February 2020, when Republican leaders publicly said not to worry while privately buying stocks to profit from the disease. In April, when it became clear that people from disprivileged groups were more likely to die from Covid, Republicans started opposing measures to reduce the spread. During 2020 they politicized rejection of the use of masks, using their breath as an instrument to support their campaign of harassment and intimidation.
A few weeks ago, Republicans blocked federal funding for vaccines and treatment.
They are still the disease-spreader party.
