The loonier end of the right can't bear the thought that they actually lost an election because most people didn't vote for right-wing policies, or that left-wing parties proved better at reaching coalition agreements, so they come up with various conspiracy theories to explain it. In recent times: Labour won because they bribed potential coalition partners; Labour won because they spent taxpayers' money on pledge cards; and (racist as well as ugly) Labour won because they got their corrupt darkies to rouse up the ignorant untermenschen of south Auckland through bribery and influence-peddling.
The above may prompt laughter among the not-criminally-insane, but they're taken seriously by a significant proportion of the right-wing bloggership. Over at Public Address, Graeme Edgerley's just taken apart the last one and demonstrated it clearly as a lie in his post Things that aren't true - see Thing 2.
