In Brazil, voting is mandatory, but people can still choose to vote in protest by pressing the blank ballot.

In the last presidential elections, voter apathy reached an all-time high, with 29% of voters intending to vote blank, according to the pre-election polls - a number that would surpass all candidate votes.

But when people vote blank, they give up their right to have it their way, and when they do this, it means they let others choose on their behalf.

Burger King wanted to change this, so the brand let people try the taste of voting blank, using BK’s most famous burger: the Whopper. And by doing so, we encouraged people to have it their way, by showing them that when they vote blank, they can't complain about the results.

We wanted to show that casting a blank ballot is not as great as it sounds. Each and every one of us deserve our country our way– and an informed voting decision is the first step in that direction. So we created a special burger to draw attention to what can happen if you let someone else decide for you, and have no say in what you want as a voter: the Blank Whopper – a new and different kind of Whopper.

Basically, blank voters who took part in this activation, received 2 buns with mayo and onion, with this message on its wrap: this is a Blank Whopper, made with ingredients chosen by someone else. When you let someone choose for you, you can’t complain about the results.

The stunt was recorded and became a 1-minute video which we launched during the biggest television debate of Brazil’s presidential run.

Featuring an exclusive report, the advertising campaign for media came out in sync with the airing of the commercial during a break at the presidential debate on Sunday evening. Later it extended to a range of other channels, from the ones covering politics to editorials on topics such as international, advertising, economics, social, and so on. The campaign was not limited to the local Brazilian press: the agency has a strong PR work abroad, as is hardly ever seen among Brazilian campaigns. Over a week, with a more intense PR work, dozens of interviews were arranged – by the agency’s main creative professional and the client’s marketing team – at the most relevant and influential papers, with the Blank Whopper receiving the highest notice and praise from the country’s most respected commentators.

Twelve days before the elections, we went to one the most iconic avenues in Brazil, where grassroots political protests are regularly held.

We placed a replica of the machine where people vote in front of a BK restaurant, but with no number and only two buttons: blank vote and confirm.

Then, we asked people for whom they would vote for in the presidential election, and those who declared the intention to vote blank got a surprise after voting blank in our replica. They received a Whopper, but when they bit the burger, it wasn’t what they were expecting: two buns filled only with onions and mayo.

After feeling this unexpected taste, they found out the message printed on the Blank Whopper’s wrap, which said: this is a Blank Whopper, made with ingredients chosen by someone else. When you let someone choose for you, you can’t complain about the results.
