Jonathan Rauch: “Only four candidates have a shot next year. They are President Bush, retired Gen. Wesley Clark, former Vermont Gov. Howard Dean, and Sen. John Edwards of North Carolina. The rest are history. Sorry, Dick. Sorry, John. Sorry, Dennis, Joe, Carol, and Al. Turn off the lights behind you. . . .
“With only one exception since the presidency of Theodore Roosevelt, no one has been elected president who took more than 14 years to climb from his first major elective office to election as either president or vice president.
“George W. Bush took six years. Bill Clinton, 14. George H.W. Bush, 14 (to the vice presidency). Ronald Reagan, 14. Jimmy Carter, six. Richard Nixon, six (to vice president). John Kennedy, 14. Dwight Eisenhower, zero. Harry Truman, 10 (to vice president). Franklin Roosevelt, four. Herbert Hoover, zero. Calvin Coolidge, four. Warren Harding, six. Woodrow Wilson, two. William Howard Taft, zero. Theodore Roosevelt, two (to vice president). The one exception: Lyndon Johnson’s 23 years from his first House victory to the vice presidency.”
The whole thing is worth reading.
