With split decisions in the Democratic contests so far -- Obama won Iowa and South Carolina, Clinton won New Hampshire and Nevada -- there is increased speculation that the nominating race will extend beyond Feb. 5 when more than 1,600 delegates are at stake.
Obama needs to steadily build on his newfound momentum if he is to upstage Clinton and become the first black US president. Kennedy's endorsement increases the pressure on Clinton, the former first lady who hopes to be the first woman to occupy the Oval Office.
