elector

'she gets to choose' is the definition.
I can't judge whether this defines the answer.

'electronic reader' is the wordplay.
'electronic' becomes 'e' (as in e-mail or e-books).
'reader' becomes 'lector' (synonyms).
'e'+'lector'='ELECTOR'

Can you help me to learn more?

(Other definitions for elector that I've seen before include "Crosses" , "One may make one cross" , "Citizen with a right to vote" , "one with a voice" , "Voter - old German prince" .)
