Democrats controlling the California Assembly appear to be two Republican votes away from passage of a delayed state budget. The GOP votes needed to deal with a $23.6 billion revenue shortfall are proving hard to get. Governor Gray Davis says he has secured two of the four Republican votes needed for a two-thirds Assembly approval of the budget. The other 28 Assembly Republicans signed a letter to Davis Thursday pledging to stick together. The Assembly is scheduled to meet Monday to renew debate on the $99 billion package passed in the Senate.
