From the article:
In March 1932, the German National Socialist or Nazi Party expected elections to catapult them into power. Instead, they suffered a massive slap in the face when the German people once again plumped for safe, conservative politics in the form of Heinrich Bruning’s Catholic Centre party and the German president Paul Von Hindenburg. The Nazis had to settle for a frustrating second. However, with Germany economically and politically unstable, more elections were sure to follow. The problem for the Nazis was, how could they court the electorate’s favor and win next time around?
Party officials decided the National Socialist’s radical image needed softening. The party’s leader, Adolf Hitler, in particular, came across as a firebrand revolutionary. This fact, plus his blatant anti-Semitism was off-putting to an electorate drawn to the comfortable, conservative pre-war image of Hindenburg et al. which recalled better days. So, Hitler, the revolutionary became Hitler, the Bavarian country gentleman in a media campaign orchestrated by Heinrich Hoffman. In January 1933, the Nazi’s finally achieved their goal when the newly marketed Hitler finally became Chancellor. But how much of this success was due to his image change?
