Leadership and ideology are inseparable. That is not a deflection.
Coolidge, for example, had a simple ideology: "The business of America is business.", despite the fact that no more than 10% of the population actually had a real business, About 40% were farmers, and small farms are not really a business, they are simply suppliers of raw materials at whatever the going rate was. Coolidge cared only about businessmen and did not give a shit about workers, women's rights, Blacks and farmers. He was at best a placeholder between the nincompoop Harding and the rather useless and disappointing Hoover.
