Dear ByzanTN:
The religious divide that the Western media have drawn is a red herring. The Greek-Catholics are concentrated in the far West of Ukraine. Big-O Orthodoxy prevails everywhere else, including the capitol Kyiv - a Yushchenko stronghold.
Yushchenko himself belongs to the UOC-KP and was pitcured attending services two Sundays ago with Patriarch Filaret.
A more apt religious distinction would be between the MP and the other Byzantine Rite chruches, including the UOC-KP the UAOC and our own UGCC.
Prior to the elections, all the Christian Churches in Ukraine but one called upon the government for fair elections. The exception was - you guessed it - the Moscow Patriarchate.
Anyway, by my humble reconing, religious divisions in Ukraine play a relatively minor role in the current situation.
Yours,
hal
