Teresa May Facing a Hung Parliament, page-8

Will some voters, less than impressed with Brexit or May, add insult to injury by fibbing as they respond to the Exit poll?
Many voters are of course wondering why exactly this election was taking place at all. Certainly most voters are none the wiser as to what Brexit means.

Voters that are disillusioned before during and after exiting the polling station, may still have a "protest against the system mindset".
Will be interesting to see how the exit poll compares to the final result.
