Clinton, Obama hunker down for prolonged battle for delegates

CHICAGO - With Super Tuesday leaving Senators Barack Obama and Hillary Clinton in a virtual deadlock, the fiercely fought Democratic presidential race has become a pitched battle for delegates - and neither candidate is likely to win it anytime soon. A day after Super Tuesday's 22-state battle for 1,681 delegates, updated delegate counts indicated Obama ran roughly even with Clinton in the one-day contest, a strong outcome for him given that she had long been favored to win.
