“I just voted for who the voices in my head told me to vote for.”
Of course I won't do anything like this - just funning.
A simple ‘confidential’ will likely be what I would say - if I get “exit-polled”.
Then I would look over my sunglasses (to be worn ESPECIALLY if it is already dark) and ask the pollster if they had seen my driver.
I'm not really fond of exit polling.
Give ‘em a H!: “I really don’t recall”.
