Answer:
Because the Nazis’ 25 Point Programme appealed to people all over the country from all walks of life, they became popular. Other extremist groups like the communists only really appealed to the industrial workers in Germany’s cities and couldn’t keep up.
Wealthy businessmen: were frightened communists would take their wealth away and did not want to see any more increase in support for them. To combat this, they began to give money to Hitler and the Nazis, hoping they would gain more seats – not the communists.
The middle-class: were generally quite traditional and were not convinced by the Weimar democracy. Hitler promised them a strong government and won their votes.
Nationalists: they blamed the legacy of the Treaty of Versailles and reparations for causing the depression and so lent their support to the Nazis who had promised to make Germany strong again.
Rural areas: The Nazis appealed to people in the countryside - especially middle class shopkeepers and craftsmen, farmers and agricultural labourers.
