Initial estimates of how the stimulus might split up aid to state government. Here is a table.
I was thinking CA would get about $20 billion for the non-infrastructure piece, but it looks like the total will be less than $21 billion inclusive of infrastructure spending (about 11% of the US total). Not sure of the underlying formula, but just splitting this based on population would imply about $3 billion more for California. Of course this is far from a final figure, but it looks like the legislature may need to cut more from the state budget than I originally thought.
