I'm a little stuck... Click here to teach me more about this clue!

'ex-president' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'failing in style' is the wordplay.
'failing' is an anagram indicator.
'in'+'style'='instyle'
'instyle' anagrammed gives 'YELTSIN'.
