Another brief aside: Ukraine

I don't have any special knowledge about Ukraine, except to speculate that the cleavage between Yushenko and Yanukovych strongholds looks very much like the Western parts that were once part of Poland are voting for the opposition and the Eastern parts that were under Tsarist rule for longer are more pro-Moscow.

However, from Instapundit I found this link to some election statistics, including turnout changes between the two rounds of voting. This is apparently one of the pieces of evidence supporting claims of ballot-rigging.

The turnout rose sometimes considerably on November 21, in regions where Viktor Yanukovych the pro-Moscow candidate gained massive support. In areas supporting the opposition candidate Viktor Yushenko, turnout practically stayed unchanged from the first round of voting on October 31.
