Governor Tim Kaine announced plans to cut

It's the fourth time in less than a year that Kaine
has had to scale back the two-year budget that runs
through next June.
On Wednesday, Kaine said the state has made some tough
choices, and more tough choices are ahead. But he said
the state is "well-positioned" to weather the downturn
in the economy.
Kaine said this re-forecast will require the state to
