No, it's not an electrical problem, but a much more potent political crisis that's knocked Power out at Barack Obama's headquarters. Responding to harsh criticism from Hillary Clinton's campaign for comments that Obama's rival is a "monster," top foreign policy adviser Samantha Power has resigned, effective immediately.

"With deep regret, I am resigning from my role as an advisor the Obama campaign effective today," Power said in a statement released by the campaign. "Last Monday, I made inexcusable remarks that are at marked variance from my oft-stated admiration for Senator Clinton and from the spirit, tenor, and purpose of the Obama campaign. And I extend my deepest apologies to Senator Clinton, Senator Obama, and the remarkable team I have worked with over these long 14 months."

Clinton's camp had put pressure on Obama to fire Power, with Florida Democrat Debbie Wasserman Schultz calling the comments "distasteful" and "inappropriate." Power is not the first casualty of unfortunate comments during the presidential campaign. Most recently, Clinton's top New Hampshire adviser, Billy Shaheen, stepped aside after suggesting Republicans would use Obama's past drug use against him in a general election.
