It Was Either Non or No

This EU constitution was going to fail anyhow. While most would not have predicted French rejection at the time of signing, British rejection was much more plausible and would be certain now. Is the US better off that it is non, not no? I think so. If the more US friendly Britain were the cause of rejection, she would have been somewhat marginalized as a result (this may have been Chirac's ideal outcome).

The question remains, how the US would be affected if the EU constitution is actually implemented? My uneducated guess is that the net expected outcome would be negative. In foreign affairs, the EU (as opposed to its member states) until now has defined itself primarily against the US. Strengthening the EU in foreign affairs at the expense of its member states should predictably harm US interests.
