… in short, that is correct — I'm as dynamic as the very best governments? (13)

I believe the answer is:

meritocracies

'as the very best governments?' is the definition.
(the most democratic form of government)

'in short that is correct i'm as dynamic' is the wordplay.
I cannot really see how this works, but
'that is' could be 'ie' (synonyms) and 'ie' is found in the answer.
This may be the basis of clue (or it may be nonsense).

I've seen this clue in The Guardian.
