The dominating party in Japan for more than 50 years may break down from the inside. The Prime Minister Taro Asou has been pressured by his party to resign. The last two prime ministers who lasted only a year caused an anti-LDP mood in Japan.
I believe that LDP should not change a Prime Minister Asou at this point. That is because to swap a prime minister within a year is a main reason they lost a support from voters. It is easy for LDP to pressure a prime minister to resign, but hard for LDP to regain votes.... They should think how to be trusted from voters!
