Our current president has done nothing but uphold the Constitution and laws of the US, with his own views, as every other president has. Not liberal enough for many, not conservative enough for others.
First, there will be orderly transition, unless you interfere. If you really think a US president would try to hold power by force, you are an idiot. Of course, we The People do still have the tools required to enforce an election, should that become necessary. Trust but verify.
Second, so many people are fond of saying President Obama isn't a Christian, because they forget that they condemned him for listening to baptist preacher Jeremiah Wright. He is a Christian, not that being something else or nothing at all is a disqualification from being a good president.
Third, Nazis were extremist, but not really right, not really left. The use of "socialist" was a poor word choice by Hitler, since he strongly believed in private property and the initiative it brings, and that destiny was controlled by a small group of people. He was anti-democratic, and obviously believed this ideal applied to his chosen people. He was not a traditional socialist and disavowed Marxist socialism, because it adhered to democratic principles and eschewed private property (exactly the opposite of Hitler's poorly-informed view of economics.)
Fourth, hitler was an occultist who used Christianity as a weapon and reason to do bad things - he was not the first nor last to do so.
Finally, you can't really categorize someone who was inconsistent - the only thing Hitler consistently was, was a delusional politician bent on getting and holding power.
