<P> In United States government, the line - item veto, or partial veto, is the power of an executive authority to nullify or cancel specific provisions of a bill, usually a budget appropriations bill, without vetoing the entire legislative package . The line - item vetoes are usually subject to the possibility of legislative override as are traditional vetoes . </P> <P> Forty - four states--with Indiana, Nevada, New Hampshire, North Carolina, Rhode Island, and Vermont as the only states that do not grant such powers--give their governors some form of line - item veto power . The Mayor of Washington, D.C. also has this power . </P>

If the line-item veto were constitutional how would it affect the balance of power explain
