Rigged elections

It seems Eduard Shevardnadze, the former Soviet foreign minister turned Georgian president, presided over parliamentary elections in which there was widespread voting fraud. Now he's out of a job, and possibly out of the country. I wrote earlier today of the lack of a sense of loyal opposition in some countries. Election fraud is often a part of this. On the other hand, one could argue that we have rigged elections of a sort here in Canada. It's called the first-past-the-post electoral system. What else would one call it when a party receiving only between 38 and 43 percent of the popular vote repeatedly wins a majority of the seats in the House of Commons and all of the political power?
