Somewhat undelectable pick (5)
I believe the answer is:
elect
'pick' is the definition.
(to elect is to pick or select)
'somewhat undelectable' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'ELECT' can be found hidden inside 'undelectable'.
(Other definitions for elect that I've seen before include "Choose by vote" , "Bring to office" , "special people" , "Vote to put into power" , "Choose; singled out" .)
