I think your analysis is right here. We won't turn into Nazi Germany because he won't have a willing military to do so. If he had a willing and able military he would no doubt turn it against anyone he deemed unworthy or a threat to him. However, we will become an even more illiberal democracy than we already are, similar to what Orban has built in Hungary. We will have state propaganda similar to Orban via Fox News, Twitter, Breitbart, Tick Tok, and other outlets that he either has control over now or soon will. As well, the usual tenants of our illiberal democracy like the electoral college, the Senate, gerrymandering, the supreme power of the Supreme Court, and voter suppression laws and actions will continue to erode our democracy and democratic institutions.
We will be an eroding democracy like Orban has done in Hungary if Trump gets 4 years of unchecked power. If you're terrified of that like I am please, I implore you, to signup to volunteer with the Democratic Party GOTV operation. Visit www.michigandems.com/volunteer to sign up. You can door knock, make calls, and more to help get out the vote. Don't let democracy slip away!
