Compare Liberal Eisenhower with Reagan finally (5)
I believe the answer is:
liken
'compare' is the definition.
(I know that compare can be written as liken)
'liberal eisenhower with reagan finally' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'eisenhower' becomes 'Ike' (Ike was a nickname of President Dwight Eisenhower).
'with' is a charade indicator (letters next to each other).
'finally' says to take the final letters.
The last letter of 'reagan' is 'n'.
'l'+'ike'+'n'='LIKEN'
(Other definitions for liken that I've seen before include "Represent as similar" , "Compare" , "Point out the resemblance (to)" , "Equate" .)
