Is Trump's 'cracked up' expression a special AmE version of the idiom?

Question

The British Press have pointedly made reference to Mr Trump's quote :

"I think I would have said that the European Union is not cracked up to what it’s supposed to be,"

What would have been expected on this side of the pond is something like

"the EU is not all that it is cracked up to be"

Speaking in extempore it is easy (as I find) to mix one's metaphors or to muddle one's words. Here, Mr Trump (I think) has actually said the opposite of what he wanted to say.

The OED gives the verb form 'crack up' as a complimentary formation. So if the EU is not cracked up to 'what it's supposed to be' that means that it deserves to be cracked up some more. Which is not, I think, what was meant to be said.

8. trans. crack up: to praise, eulogize (a person or thing). So to crack into (repute, etc.) Also (in pass.), to be reputed (usually in negative sentences). colloq. 1829 Kentuckian 28 May He is not the thing he is cracked up for. 1835 D.

OED

The British Press pointed out the discrepancy of wording but did not pick up on the reversal of the phrase. So, I wonder, is there an AmE version of the BrE 'not all it is cracked up to be' that is the opposite ?

And, if so, when did we diverge from one another ?

As far as British use is concerned I endorse what you say. Almost always it is used following a negative. "The EU is not all that it is cracked up to be" is what I believe Trump meant to say. (Though I for one do not agree with him).

If Trump indeed said that, he said it like an immigrant would have. It's not at all idiomatic in the US. (Though I will say that the "not all it's cracked up to be" idiom is used in the US mostly without any comprehension of what "cracked" means in this case.)

Answer 3

It is unclear whether the question asks for a trans-pond translation of the opposite sentiment or whether it wants similar usage. In the latter case, I suggest that one AmE version of the BrE

it is not all it is cracked up to be

is

it sucks
