The Clintons are largely responsible for the democratic party's tolerance and enabling of fascism. They are responsible for popularizing thirdway politics in the US, and making compromise the Democrats only real priority.
Of course they are going to endorse the center right, that is the party platform that they've been building since the 90s. I honestly do not know why the conservatives demonized Hillary so much, the Clinton's basically built their empire compromise by compromise.
It's a bit pedantic to say that Hitler rose to power without the majority because he only received 43.9% of the vote..... especially considering that over 17 million people voted for him and the next most popular candidate only received 7 million votes.
That really only makes sense if you are reviewing the election through the lens of someone used to a two party system. If we are going to evaluate it as if it were a two party system and combine the right and left into two coalitions......the Nazi, Centre, DNVP, and BVP would make up nearly 26 million voters while the SPD and kpd would only make up nearly 12 million people.
Even though the Centre party was much more willing to work with the Nazi than the socialist, if we added their votes to the left coalition you'd still have 22m on the right and 16m on the left.
The only way you can really claim that the Nazi didn't receive the majority of the vote is if you misinterpret The Weimar Republic as a direct democracy and not a Republic.
