George Gresham was one of the first guests to arrive at Mayor de Blasio's inauguration. The president of the powerful health care workers union SEIU-1199 took a seat in the front row of the VIP section, tucked himself under a blue blanket and stared up at City Hall with a serene look on his face. "I've never been as excited to be there since 1990," Gresham said last week. "Maybe because it's been 20 years of Republican leadership, but more than that, I think it's because this is a progressive candidate and that's the core of who he is."
