The Republican Party held its fourth presidential debate in Milwaukee, Wisconsin on November 9, 2015. Eight candidates participated in the main debate: Donald Trump, Dr. Ben Carson, Sen. Marco Rubio, Sen. Ted Cruz, Gov. Jeb Bush, Carly Fiorina, Gov. John Kasich, and Sen. Rand Paul. The transcript of the debate can be found here. EffectCheck® can provide insights into the lexical emotional tone set by each of the candidates.
Each of the candidates had approximately “equal time” in that the number of words spoken by each varied from a low of about 1725 (Carson) to a high of about 2300 (Rubio and Kasich). The figure below shows a pie chart with the percentage of overall contribution for each of the candidates.

In addition to the difference in evoked levels of compassion and happiness between Sen. Rubio and Ms. Fiorina, note that Sen. Rubio was the only candidate whose evoked level of confidence was higher than the evoked level of depression.
Individual candidates may stand out with respect to specific emotional profiles; however, Sen. Rubio’s language stands alone in several regards. The overall emotional profile from Sen. Rubio’s contributions to the November 9, 2015 Republican Debate shows a clear difference to that of his rivals, emphasizing greater confidence, compassion, and happiness, with lower depression.
