National/common/unifying language for the US?

As you may have heard on Language Log, on May 17th-18th, the US Senate approved not one but two amendments - one Republican, one Democrat - on the status of English. The first amendment, by Sen. Inhofe (R-Oklahoma), amends sections 161-2 of Title 4 of the United States Code to state:

English is the national language of the United States. The Government of the United States shall preserve and enhance the role of English as the national language of the United States of America. Unless specifically stated in applicable law, no person has a right, entitlement, or claim to have the Government of the United States or any of its officials or representatives act, communicate, perform or provide services, or provide materials in any language other than English. If exceptions are made, that does not create a legal entitlement to additional services in that language or any language other than English. If any forms are issued by the Federal Government in a language other than English (or such forms are completed in a language other than English), the English language version of the form is the sole authority for all legal purposes.

The second, by Senator Salazar (R-Colorado), makes the same section rather more reasonably, if vacuously, say:

English is the common and unifying language of the United States that helps provide unity for the people of the United States. The Government of the United States shall preserve and enhance the role of English as the common and unifying language of America. Nothing herein shall diminish or expand any existing rights under the law of the United States relative to services or materials provided by the government of the United States in any language other than English.

The bill is still under debate, so it remains to be seen what, if any, of this will be left - but, after 230 years of doing just fine without one, the USA may or may not soon have a national language. Either way, it's an interesting debate to follow. I remember in San Francisco just about any governmental document seemed to be printed in English, Chinese, and Spanish; that approach - choosing the language according to what people actually spoke on a local level, rather than a national one - strikes me as eminently sensible. What I can't seem to figure out is what the plan is now that both have passed - do they stick both texts in the section, or do they just hash it out later?
