Let's say I'm trying to force you to vote for my candidate. Am I going to be happy with you taking the option of going to the polling place to vote privately? No. You'll do it right here where I can watch you click the button for my guy.
Let's say you're in the voting booth and have taken the picture. You can then do at least one of the following:
- Exchange your ballot for a blank one and fill it out again
- Fill in the check box and vote for your real candidate
- Spoil your vote
