As the Supreme Court readies to hear oral arguments in California v. Texas, the Trump-Republican lawsuit to completely dismantle the Affordable Care Act, Americans’ health care hangs in the balance. If successful, the lawsuit would rip coverage from more than 20 million Americans and remove protections for the 135 million people with pre-existing conditions — all in the midst of a deadly pandemic. For a decade, Republicans have waged a war on health care by undermining the ACA at every turn. Now, Donald Trump and Senate Republicans have installed what they hope is an anti-ACA justice on the Supreme Court who they believe will help them accomplish what they haven’t been able to do legislatively — repeal the entire ACA and throw the American health care system into chaos. If Republicans get their way, the protections of the ACA that so many Americans rely on will be gone.
