ROK presidential rivals make final election pitch

Race looks set to go down to the wire: pollsters

The two rivals for the Republic of Korea's presidency made a final pitch to voters on Tuesday, on the eve of an election that looked set to go down to the wire and could produce the country's first female leader.

The winner of Wednesday's ballot will face numerous foreign and domestic challenges, including the Democratic People's Republic of Korea, a slowing economy and soaring welfare costs in one of the world's most rapidly aging societies.
