Sen. Barack Obama’s grandmother has passed. I’m sure Michelle Obama feels badly for not accompanying her husband to Hawaii to say her goodbyes.

Barack Obama’s grandmother, who helped raise the Democratic presidential candidate in Hawaii, passed away Monday after a prolonged battle with cancer. Madelyn Dunham, 85, had been gravely ill for weeks, prompting Obama to interrupt his campaign for a few days last month to visit her in Honolulu, Hawaii.

“She was the cornerstone of our family and a woman of extraordinary accomplishment, strength and humility,” read a statement from Obama and his half-sister, Maya Soetoro-Ng. “Our debt to her is beyond measure.” (Source)
