Its to discourage voting at the end of the day....
Well, sorta. It's to discourage voting for the people who bombed kids, supported rapists, supported ICE, increased funding to the US military, funded torture and kidnapping programs, etc. Luckily there are other options than those.
It's also meant to discourage people from only voting, and then going back to brunch as soon as the "Good child-bombers" get elected.
