How strong is party loyalty when going through a severe crisis like the 2020 Covid-19 pandemic? Using unique and identical panel data from Sweden and Denmark, collected during the Covid-19 first wave in the spring and early summer of 2020, I explore the stability of party loyalty as a response to the Covid-19 pandemic. While being very identical universal welfare states on central parameters as well as both possessing a social democratic government in place at the time of the Covid-19, Sweden and Denmark nevertheless opted for two very different pandemic strategies when the Covid-19 pandemic hit. Where Denmark opted for a rigid lockdown, Sweden remained mostly open, resulting in death tolls that differed increasingly during the first wave of the pandemic. I explore if these different contexts mattered for party loyalty in the two countries, and how this might have shifted as the pandemic unfolded in the summer 2020, yielding different death tolls in the two countries.
