Per Clay spokesman Steven Engelhardt, Missouri Governor Jay Nixon is endorsing Rep. William "Lacy" Clay (D-St. Louis) in the 1st District congressional primary in St. Louis.
When Carnahan announced his entry into the 1st District race, Clay told the St. Louis Beacon that the "friendship was over" between he and Carnahan.
Clay commented on the endorsement today during an interview with our host Don Marsh of St. Louis on the Air.
Clay said Nixon told him "there was no one better for this position" and that he and Nixon had been discussing the matter "for the last several weeks."
Clay has also been endorsed by St. Louis Mayor Francis Slay and St. Louis County Executive Charlie Dooley.
