What will happen to Japanese politics?

  Today's highest temperature was about 27 degrees, but the sky was blue all day and it was really an autumn-like day.

  Japanese political situation is still chaotic. In Japanese Democratic party convention which will be held soon, some congressmen are going to run for the head of the party. Mr.Hosono, who many party members wanted to run for it, turned it down, and Mr.Noda, the current prime minister,will be the safest candidate. But there is frustration in the party because  the Democratic party is now very unpopular among common people according to the recent poll. The prime minister has promised that he will dissolve the Diet in near future. If the Diet is dissolved, the general election will be held, and, as a result, it is expected that the Democratic party will be defeated.
  The largest opposition party, the Liberal Democratic party, will also hold the convention this month, and it is expected that Mr.Tanigaki, the present head of the party, will not be reelected. An influential new party is going to be born, being led by Mr.Toru Hashimoto. What will happen to Japanese politics?
