If Hillary Rodham Clinton is going to win the Democratic presidential nomination it looks like she may need a couple of landslides.
She needs 57 percent of the remaining primary and caucus delegates to erase the lead that Barack Obama has amassed.
Obama's victories in Wisconsin and Hawaii yesterday were his ninth and 10th in a row and give him 1,178 pledged delegates in The Associated Press' count. Clinton has 1,024 -- a deficit of 154.
More than 1,000 delegates remain to be awarded, most of them in contests in 14 states, Guam and Puerto Rico. Obama appears well-positioned to win at least one remaining state -- Mississippi. It fits a pattern of Southern states with large black populations that he has won handily.
