re: #510 Dark_Falcon

In 1976 and 1992, the incumbent Republican faced a primary challenge, as did Carter in 1980. That is why I used the phrase “an incumbent president who did not face at least a notable challenge”.

a primary challenger is a symptom of vulnerability, not a cause

the fact is that from the 20s onward, eisenhower was the only republican president who did not leave the economy weaker when they left office than when they came in, and that’s why so many of them were one term presidents
