Why had the Nazis not got into power by 1928?

they were not in power because they did not have full power over the parliment and even though they were popular they had not won over all the germans as in 1933 they had only won 45.3% of the votes and from there they started to grt in power A. because people were scered of him and voted for him in fear and B. because he forced people to vote for him also people were scared of him as he was very curl to the jews from my views i think that Hitler is racist and i am glad he lost WW2 :) x
