Senate race In 2004, John announced he would not run for re-election to his House seat but would instead run for the seat in the
U.S. Senate being vacated by popular Democrat and fellow Crowley native
John Breaux, who endorsed him. John, however, was defeated by Republican
David Vitter of the
New Orleans suburbs in the primary, Vitter garnered 51 percent of the vote, compared to 29 percent for John. The remainder of the ballots was split between then
State Treasurer John Neely Kennedy and the
African-American then-state senator Arthur Morrell, both Democrats. John's seat in the House fell into Republican hands, as
Charles Boustany won the 7th district with 55 percent of the vote against Democrat
Willie Landry Mount. Kennedy later switched parties and succeeded Vitter as senator in 2017. ==Post-political career==
