Patrick Hayward "Pat" Caddell (born May 19, 1950) is an American public opinion pollster and a political film consultant who served in the Carter White House, and in many other presidential campaigns.
Caddell was born in Rock Hill, South Carolina. He has worked for Democratic presidential candidates George McGovern in 1972, Jimmy Carter in 1976 and 1980, Gary Hart in 1984, Joe Biden in 1988, and Jerry Brown in 1992. He also worked for Colorado Senate candidate Andrew Romanoff in 2010. Caddell persuaded Jimmy Carter to focus in 1976 on the "trust factor", rather than divisive political issues in the 1976 campaign, a strategy which led, narrowly, to victory. The Arkansas political scientist and pollster Jim Ranchino declared the then 26-year-old Caddell "the best pollster in the business." According to researchers, Caddell had wide influence in the Carter White House, and was the chief advocate of what later became known as Carter's "malaise speech".
Caddell has served as a consultant to various movies and television shows, most notably the movies Running Mates, Air Force One, Outbreak, In the Line of Fire, and the serial drama The West Wing. He was also a marketing consultant on Coca-Cola's disastrous New Coke campaign.
