"Politically, Davis was a staunch conservative, who detested socialized medicine and any other form of government intervention in medicine. He was quite outspoken with hidebound views on issues medical and nonmedical. Although personally aloof, Davis took a liking to his new son-in-law when Nancy married Ronald Reagan in 1952. The father-in-law enjoyed sharing his political views with the actor, and many sources credit Davis with being among the most important people in the transformation of Ronald Reagan from a liberal Democrat in the 1940s into the conservative Republican he became in the 1950s and for the rest of his life."
Upon the death of Nancy Reagan, Cory Franklin in The Chicago Tribune discusses "the second most important person in her life."
