Grammarly Study Gives Top House and Senate Candidates a 92 for Clarity

Language Analysis Tool Examined Campaign Sites for 33 Writing Errors Known to Confuse Readers

SAN FRANCISCO--()--More than 9 out of 10 candidates in the 10 most hotly contested house and senate races are clear and straightforward in their political positions, according to new findings from Grammarly, the world’s leading automated proofreader.

Grammarly analyzed campaign websites to gauge how clearly candidates communicate their stances on issues. The company found that candidates are clear, with a median clarity score of 92 percent. All candidates scored 80 percent or above. Republican David Perdue, candidate for one of Georgia's U.S. Senate seats, topped the study with a perfect score.

The Alaska Senate race holds the distinction of the nation's clearest political contest with Republican Dan Sullivan scoring a 99 and Democratic challenger Mark Begich scoring a 94. While there was a wider dispersion among candidates’ clarity scores, the parties overall were very close with Republicans narrowly edging out Democrats by a 93 - 91 margin.

"Grammarly’s software provides a unique perspective on how candidates use language," said Grammarly CEO Brad Hoover. "Following candidates’ language helps voters make an informed choice." Added Grammarly Chief Linguist John McWhorter, "Clumsy prose is often a clue that a writer either has little to say or is trying not to say something too directly.”

Grammarly created a special algorithm to screen text for 33 errors that can lead to ambiguous or confusing writing, such as redundant prepositions, wordiness, an incomplete comparison, unclear antecedent and squinting modifiers. The tool produces a clarity score by normalizing the number of mistakes to text size. Candidates that do not post specific positions on issues on their campaign website were excluded from the analysis.

Key findings include:
