Well designed ballot layouts allow voters to make their intentions clear; badly designed ballots invite voters to make mistakes. This year, the Florida Senate race may be decided by a misleading ballot layout—a layout that violated the ballot design recommendations of the Election Assistance Commission. In Miami, Florida in the year 2000, the badly designed “butterfly ballot” misled over 2000 voters who intended to vote for Al Gore, to throw away their vote. (That’s a strong statement, but it’s backed up by peer-reviewed scientific analysis.) In Sarasota, Florida in the year 2006, in a Congressional race decided by 369 votes, over 18,000 voters failed to vote in that race, almost certainly because of a badly designed touch-screen ballot layout. In Broward County, Florida in the year 2018, it appears that a bad optical-scan ballot design caused over 26,000 voters to miss voting in the Senate race, where the margin of victory (as of this writing, not yet final) is 12,562 votes.
