The war of words between Sens. Hillary Clinton and Barack Obama has intensified in recent days.
(CNN) - Just a couple of weeks ago, Sen. Hillary Clinton said she wasn't interested in attacking her opponents - she was interested in "tackling the problems of America."
But with her lead slipping, things have changed, and the New York senator has found herself in a full out verbal war with Sen. Barack Obama.
"In politics, you can afford to ignore your opponents until you start to feel them breathing down your neck," said CNN's senior political analyst Bill Schneider.
