Birch Bayh, the incumbent Senator, faced no opposition from Indiana and avoided a primary election. Bayh was originally elected in 1962 and re-elected in 1968 and 1974. He was Chairman of Senate Intelligence Committee and architect of 25th and 26th Amendments. This election was one of the key races in the country, and signaled a trend that would come to be known as Reagan's coattails, describing the influence Ronald Reagan had in congressional elections. Incumbent three-term Senator Birch Bayh was defeated by over 160,000 votes to Representative Dan Quayle, who would later go on to be Vice President of the United States.
