Remember the poisoned Viktor Yushchenko?

Voters look set to deal President Viktor Yushchenko a rebuff in a parliamentary election next Sunday that could tilt their divided country back toward Russia just 16 months after a revolution that appeared to move Ukraine closer to the West.

It's a bitter twist for Yushchenko, whose Orange Revolution ushered in the very reforms that are making this contest the most democratic in the former Soviet republic's history.
