Russian Voting Statistical Anomalies, from Kim Zussman
There's an interesting WSJ article on recent Russian parliamentary election (subscription required for now though):
Data analysis shows higher % voting for the "United Russia" party in districts with round numbers of voter turnout (ie, 70%, 75%, 80%, etc) as well as for districts with unusually high turnout (>=98%). Strongly suggests ballot stuffing, manufactured counts, etc.
Evidently vaunted Russian mathematicians are not part of the current apparatchik.
