Require that congressional budget bills include a debt ceiling level that corresponds to the current debt level, pls any new borrowing that would be required under the new budget being passed, plus a contingency of, say, 20% for unforeseen events (..or market collapses from big oil spills...or market effects of devastating natural events, etc). The budget and corresponding debt limit should be passed at the same time. No more ridiculous debt limit fights.
current federal budget stays in place until a new one is agreed to and passed, indefinitely if need be. No more gov't shutdowns.
Net effect - congress can only pass/repeal/modify bills through regular legislative order as prescribed by the constitution.
