NERVOUSNESS has replaced euphoria among supporters of Democrat presidential candidate Barack Obama as a new poll shows him in a dead-heat with his Republican rival.
Each contender is on 46%, according to Rasmussen Reports.
Gallup gives Mr Obama a lead of just three points.
He will use a whirlwind tour of Europe, the Middle East, Iraq and Afghanistan to persuade wavering voters he is a credible commander in chief.
Republican candidate John McCain trails Mr Obama in most polls but his campaign has not been sunk by the unpopularity of President Bush.

Akey risk for Mr Obama is that as he woos undecided voters he risks alienating the young, predominantly liberal voters who have funded his campaign and secured his nomination.
Already, he has outlined social positions that put him to the right of many UK Conservatives.
He supports limited use of the death penalty, has backed controversial surveillance legislation supported by the Bush administration, and his commitment to pulling troops out of Iraq has become more nuanced. …
