If there is one thing contributing to Prime Minister Taro Aso's sagging approval rate, it's his flip-flopping on the issues.

Since his inauguration in September, Aso's stance-switching has been jumped on by the media, giving ammunition to his opponents and throwing his party into chaos.

Most recently, Aso shocked the political world by saying he was originally against postal privatization when, in 2005, he was a Cabinet minister under then Prime Minister Junichiro Koizumi, who championed that goal.
