Sort of. He had a diverse coalition, but as he got more support from one group he would lose support from many others. This gave a rather ironic electoral college result where all the big northern cities were cancelled out by rural areas leaving Stevenson's only EVs from the south. This basically meant that he had the support of the most loyal democrats at the time and not many others.
One interesting note is that many segregationist supported Ike in 1952 but not in 1956, as shown by South Carolina and Mississippi having Ike on the ballot as an independent in 1952 but there was an unpledged electors movement of Harry Byrd and T Coleman Andrews in 1956. Also, as I noted in my previous topic, Ike did well among southern blacks in 1956, but not 1952.
And several of the Northern cities, such as San Francisco, Chicago, Baltimore, Pittsburgh, and Minneapolis, voted for
Eisenhower in 1956, who also came close in New York City.
