Whitfield was a member of the moderate Republican Main Street Partnership. On his official website, he represented himself as a conservative who has consistently voted anti-abortion and "supports allowing students to engage in voluntary school prayer." He also lists military issues and encouraging the continued use of coal and nuclear as an anchor for baseload power to insure the use of an abundant, affordable and reliable source of electricity in the United States. The Sunlight Foundation reported in 2008 that among the 435 members of the U.S. House of Representatives, Whitfield had the seventh-highest amount of investment in oil stocks. Whitfield was Co-Founder of the United States Turkish Caucus in the United States Congress. Recognizing the important role Turkey plays as the only Muslim Nation in NATO and having had many conversations with commanding generals of the 101st Airborne Division at Fort Campbell, Kentucky, Whitfield thought it was important to form a Congressional entity to provide support for Turkey in its role as a NATO Member.
