This election could mean a major jump to a much more Western-style system in Japanese politics -- that's revolutionary.

I think this will significantly change the LDP.

If Koizumi wins, his party is not going to be the old LDP, ... Koizumi has become able to call the shots and in the future, no matter who is prime minister, the back benchers will be hesitant about defying policy made by the leadership.

He's purged the party of recalcitrant anti-reformers at least in one field, and others will get the message, too.

I think this will significantly change the LDP,

Party label and leadership image become more important...and thus who leads the party and what the party stands for, which can be communicated to a large number of people only by media, especially TV, becomes a more important factor.
