One major swing group that is often courted by the Republican party is business leaders with the promises of less regulation and lower taxes. Show the strength and support of major business leaders like CEO's of Fortune 500 companies, ideally pick someone influential to name to a major cabinet position before the election to prove that it's not just empty rhetoric.
Robert McNamara who went from being CEO of Ford to Secretary of Defense is a great example of this, and helped mediate hawkish tensions during the Cuban Missile Crisis.
