She’s proven that she cares more about “Hillary” than “unity.” More about defeating Obama than defeating the Republicans. She’s become a political suicide-bomber, happy to blow herself to bits — as long as she takes everyone else with her. On Friday, one of Barack Obama’s foreign policy advisors, Samantha Power, resigned after calling Senator Clinton “a monster” during an off-the-record exchange. It was an unfortunate slip, but one that echoed the sentiments of many Clinton apologists like me — who’ve watched Hillary’s descent into pettiness and fear-mongering with the heartbreak of a child who grows up to realize that his beloved mother has been a terrible person all along. Are the conservatives right about the Clintons? Will they do and say anything to get elected? I don’t know. All I know is…I’m through apologizing.
