“As your Senator for District 35, I've always stood firm on my commitment to being a fiscally conservative leader who prioritizes the safety and prosperity of our community. My record clearly reflects my dedication to securing our borders, staunchly supporting law enforcement and the Second Amendment, advancing educational opportunities for our kids, and promoting a strong Idaho economy.” (Mark Harris campaign website)
“In defense of our local industries, particularly in Soda Springs, I sponsored legislation aimed at curtailing frivolous lawsuits that not only threaten our businesses but also our community's livelihood. Critics dub these efforts as favoring big business, but let's be clear: these laws are about protecting common sense and ensuring that if someone disregards clear instructions or warnings, trial lawyers shouldn’t be able to exploit the legal system for easy financial gain.” (Mark Harris campaign website)
“This isn't just about protecting companies; it's about protecting jobs. In Soda Springs alone, the phosphorus mining operation—vital for producing crop inputs, products essential to agriculture nationwide—is a cornerstone of our local economy. The 800 employees at Bayer are not just workers; they are our neighbors, friends, and integral community members who contribute significantly to our local economy and social fabric.” (Mark Harris campaign website)
