Only two months ago, mayoral candidate Bill de Blasio blasted Gov. Andrew Cuomo for not doing squat to save the community hospital closing crisis being brought about by Gov. Cuomo's political appointee, the Wall Street investment banker Stephen Berger. But now, Mr. de Blasio is holding hands with Gov. Cuomo in a show of "unity." Healthcare activists question how Mr. de Blasio will be able to pressure Gov. Cuomo to reverse course on hospital closings, if they how appear to have brokered political backroom deals to support each other in the election and reelection cycle ?
