Measures by Chicago Mayor Rahm Emanuel and Cook County Board President Toni Preckwinkle to consolidate city and county services have saved $9.2 million, Emanuel and Preckwinkle jointly announced Tuesday. The biggest of these cost-saving measures is $4.3 million from the city and county working together to run elections.

Emanuel and Preckinkle started the cost-savings program when Emanuel became mayor last spring. The program has so far identified $20.5 million in total savings, a tiny fraction of the county and city budgets.

Cook County's annual expenses are roughly $2.3 billion. Chicago's 2012 budget is about $6.2 billion.
