Idaho Gov. Butch Otter is sounding a cautionary note, after November state tax revenues came in $5.4 million below projections, for a cumulative year-to-date shortfall vs. projections of $16.2 million; that's 1.6 percent below the forecast. Since lawmakers and the governor budgeted for spending well below the projected amounts, there's no shortfall, but Otter's warning that projected big budget surpluses could shrink. "The more probable scenario is for both FY 2012 and FY 2013 to continue to be years of limited growth that will require us to be very selective in the authorization of new General Fund spending," he wrote today in a letter to members of his cabinet.
