Is There Any Difference Between Foreign 'Dirt' and Domestic 'Dirt'?

It's a curious question.

Some American guy comes up to you....saying he's with such-and-such New Orleans foundation and has 'dirt' on some Republican candidate.

Some British pretender-spy comes up to you and says he's got the same basic 'dirt' on some Republican candidate. 

Is there any difference here?

No.

Some barber from Reno (an American) and some French journalist from Paris....same 'dirt' aspects....same value?  Yes. 

'Dirt' is 'dirt'.  If you haven't figured that out yet....you might want to open up a beer and think about the implications.
