Politician to keep his word ?

I’ve never paid a lot of attention to Steve Bracks, but it appears from this report that he’s going to keep a promise even though it reduces his power.

Bracks says he will introduce a proportional representation system for the Victorian Legislative Council (=Senate) and reduce its term to four years. On the plausible assumption that Labor will win the next election with a reduced majority in the lower house, this implies that minority parties will hold the balance of power in the upper house, whereas Labor now has a majority in both. If this actually happens, Bracks will rise greatly in my estimation.
