Of course adultery isn't a "plank of the conservative platform", but Scott DesJarlais, Newt Gingrich, Bob Livingston, Bill Thomas, Dan Burton, Henry Hyde, Helen Chenoweth, J.C. Watts, John Schmitz, Don Sherwood, Strom Thurmond, Ken Calvert, Randy Cunningham, Sue Myrick, Jim Bunn, Ed Schrock, Vito Fossela, Chip Pickering, Dan Crane, John Ensign, and Mark Sanford all come to mind.
