Victoria's 79 municipalities, with about 3.5 million voters, will all hold elections tomorrow, in an unprecedented state-wide operation. Local elections had previously been staggered over a three- or (more recently) four-year cycle; from now on they will all be held together, every four years, exactly midway between state elections.

For any government, this sort of simultaneous election is a risk; voters may well treat it as a giant by-election, and use it to express negative views of the state government, rather than try to assess the merits of their local unknowns. That's a particular risk this time, since federal incumbency coupled with the global financial crisis seems to have hurt Labor at state level over recent months.
