CMV: There is nothing legal the Democrats can do to prevent a Republican from taking the oath in January 2025

Someone seriously tell me I'm wrong as even though the 2020 election wasn't decided until Saturday (which a part of my anxious brain desperately wants to somehow make happen again as he may have technically claimed victory to his supporters but that was only him saying he won iirc it wasn't an official decision) since I saw some scary-ish numbers at about 11 pm Tuesday night I've been kind of having an anxiety attack not only fearing that outcome but fearing all the bad that might come from it from people talking about the sentencing like that'd make it impossible even though he still wouldn't be president for the immunity shit to apply (as the sentencing wasn't delayed past inauguration day) to fearing that Project 2025 might mean the end of everything from my favorite TV shows (as people have said to try and encourage voting amongst fans of those shows that Project 2025 going into effect would mean they get cancelled for being "pornography" due to canon gay characters) to my potential future career path (as in the kind of society people have said-where-I-don't-know-what-degree-is-fearmongering Project 2025 might lead to I'm afraid there'd be no place for an artist (I work in multiple mediums just not visual despite that being what's commonly associated with the term) who makes the kind of art I want to make) to even me living in America instead of having to move-because-there's-a-war-coming like my German great-grandparents did if you know what I mean.

Why I said a Republican in the title is I'm afraid that we couldn't just stop Trump without stopping Vance too or he'd take over that spot or w/e but barring the miracle-my-mom-said-we'd-need-that-I'm-afraid-would-have-to-be-a-literal-act-of-a-literal-god and us just getting a 2020 repeat again despite what he claimed I don't know how we-the-Democrats could stop both of them without something that'd make us look like just as much of the bad guys as we say they are

So is there anything that could be done to prevent four more years of this crap or are our only options of not lying down and taking it it stopping violently with either WWIII or a YA-dystopian-esque rebellion?
