Senator Jim Inhofe (R-OK) says he will introduce the following amendment

Beginning with Fiscal Year 2007 and thereafter, non-defense, non-trust-fund, discretionary spending shall not exceed the previous fiscal year’s levels… without a 2/3 vote.

to the “FY ’06 Labor/HHS Appropriations Bill and keep introducing until it succeeds.”I’m all in favor of not increasing discretionary spending, but, assuming this Inhofe amendment passes at some point, if at a later date, a spending increase was sought, wouldn’t it be possible to lift the requirement of a 2/3rd vote by a simple majority vote?
