Jimmy Carter, that's what. Ever heard of malaise and stagflation?
Not necessarily. A lot of Carter's problems can be laid at the feet of the disaster he appointed to be Fed Chair, William Miller, and it unlikely that anyone else, Republican or Democrat would have nominated him. To be fair, neither Carter nor anyone else could have known ahead of time that Miller would prove so inept that he needed to be promoted to Treasury Secretary to get him out of the way, but I'm convinced that all else remained the same and Carter appointed anyone else, he likely would have been reelected in 1980.
