The temporary imposition of popular relief programs in response to the coronavirus makes Republicans nervous. --- In one short month, the United States has made a significant leap toward a kind of emergency social democracy, in recognition of the fact that no individual or community could possibly be prepared for the devastation wrought by the pandemic. Should the health and economic crisis extend through the year, there’s a strong chance that Americans will move even further down that road, as businesses shutter, unemployment continues to mount and the federal government is the only entity that can keep the entire economy afloat. But this logic — that ordinary people need security in the face of social and economic volatility — is as true in normal times as it is under crisis. If something like a social democratic state is feasible under these conditions, then it is absolutely possible when growth is high and unemployment is low. And in the wake of two political campaigns — Bernie Sanders’s and Elizabeth Warren’s — that pushed progressive ideas into the mainstream of American politics, voters might begin to see this essential truth. If the electoral danger for the Republican Party is that voters will blame the president for high unemployment and mass death — a reasonable fear, given how Trump loudly denied the threat in the face of warnings from inside and outside his administration — then the ideological danger is that it undermines the ideological project that captured the state with President Ronald Reagan and is on the path to victory under Donald Trump. […] After years of single-minded devotion, the conservative movement is achingly close to dismantling the New Deal political order and turning the clock back to when capital could act without limits or restraints.
