This is in Spain, but maybe could happen here....I have my doubts about the "consensus" part however...
"MADRID -- Spanish lawmakers launched a heated debate Friday on a proposed constitutional amendment that will force the government to keep future deficits very low - a fast-track change which is designed to reassure investors fretting over the country's debt load but has infuriated unions and some opposition parties.
The amendment was expected to win passage easily after the debate in the lower chamber of Parliament, and next week in the Senate, because it is supported by Spain's two dominant parties in a rare display of consensus - the ruling Socialists and the opposition conservative Popular Party."
