An unusual opinion poll that has correctly predicted the winner of the last four presidential elections has given Democratic challenger Kerry 57 percent against 43 percent for Bush, according to results released on Wednesday.

The Nickelodeon cable channel, better known for programs "SpongeBob Squarepants" and "Jimmy Neutron," conducted "Kids Vote," an online survey of almost 400,000 children on Tuesday.

Nickelodeon, a unit of Viacom Inc., has organized its poll every election since 1988, and has a 100 percent record of picking the winner.
