This study analyzes the correlation of speeches by members of Congress who were supported by the Tea Party political movement with changes in mainstream conservative political discourse. The rhetoric of these politicians after the Tea Party’s ascendance in the 2010 congressional elections was compared to the rhetoric used by John McCain, the Republican nominee in 2008, and Donald Trump, the Republican nominee in 2016 and current President, to understand the correlation with other changes in conservative discourse. This discourse shift was studied using speech analysis to code for instances of negative discourse and establish a comparison between these election years while also noting rhetorical shifts evident among mainstream conservative politicians. The sources were five speeches delivered by John McCain during his 2008 campaign along with five speeches delivered by Donald Trump during his 2016 campaign with these five speeches being the campaign announcement speech, a speech on immigration, a speech on foreign policy, a speech to the American-Israeli Public Affairs Committee Conference, and the speech after claiming the Republican nomination, along with two speeches by Sarah Palin between 2008 and 2010 and five speeches from Tea Partiers (Michele Bachmann, Marco Rubio, Ted Cruz, Mike Lee, and Rand Paul) to test for a correlation between the Tea Party's ascendance in 2010 and increasing normalization of harmful discourse. Rhetorical strategies coded as harmful discourse were fear-inducing language, political myths, dog-whistle rhetoric, conspiratorial accusations, and personal insults.
