Open enrollment season for Affordable Care Act (ACA) plans arrives amid a severe threat from Trump and congressional Republicans —- who continue to block the extension of crucial ACA premium subsidies. These subsidies have helped middle and lower-income Americans afford health coverage since they were enacted during the Covid pandemic.  This is what the government shutdown — now in its fifth week — is all about. Democrats insist that the subsidies be extended; Trump and the GOP have refused, despite the economic pain and health insecurity their actions will inflict on everyday Americans – including millions of MAGA voters. The president and his party won’t even negotiate with Democrats to end the shutdown.
