Since Donald Trump’s election, a loose coalition of citizens, doctors, nurses, activists and others have rallied together to prevent their fellow Americans from losing health insurance. They won a big victory last month when Congress set aside its efforts to pass a destructive bill. But now the coalition has a new fight.

Trumpcare has begun, not through legislation but through executive action.

Last week, the administration took several steps to deprive people of health insurance. In doing so, it has both a short-term goal (have the federal government do less to help vulnerable citizens) and a long-term goal (sabotage Obamacare, so that Congress can more easily repeal the law).

Trump will probably accomplish at least part of the short-term goal and take insurance away from some people. But it is possible to minimize the damage, through an effective political response. Whether you’re a Democrat, Republican or independent — whether you have already been part of the citizen activism or not — I encourage you to get involved.
