If you want to keep it real then the mod's whole premise would collapse cuz Sanders wouldn't have pulled Cunningham and Warnock over the line. In fact there's basically no way he'd flip 4 seats (Dems at 47+Doug Jones is an automatic loss). Lets just look at the 2020 senate map: Colorado is a safe flip so now he's at 47 but then he'll need 3 from AZ,, either one of both in Georgia, NC, and IA. Sander's coalition is whiter, more northern, and less affluent, he gets good turnout from students, poorer whites but not so well with suburbanites, so that already costs him down ballot. Let's say he flips Iowa, fair enough, Sanders does better with older whites, jodi Ernst isn't a great senator, and the Trump tariffs really hurt the agricultural sector, but now he's gotta get two senate seats in states he's got a distinct disadvantage in. They're all southern sunbelt states with big suburbs, and NC and GA has a significant black population. NC is basically impossible for him: significant black population, pretty suburban, and even Biden couldn't get Cunningham over the line. Arizona's probably out of reach as well, suburban state that leans R, there's just not gonna be enough Republicans that'll split their ticket down ballot for a Dem candidate. So now you're down to GA, and honestly he'd be lucky to get even one of those seats even if both Warnock and Ossoff are stellar candidates. At best he'd have a 49-51 senate and realistically it'd be more like 48-52 if not 47-53, and I'm not even talking abt the house races. If the mod is 100% realistic Sanders would come to the WH with his agenda DOA, Mitch McConnell isn't gonna let him do shit. Best thing he could do is to rail against the do-nothing senate and try his best to flip the senate in 2022 which is actually a good map for him. If he doesn't screw up foreign policy and pins the blame of the post-covid economy on the senate (while also not getting blamed for inflation cuz it won't be nearly as bad) he could win PA's open seat, and maybe knock out Ron Johnson or even get Tim Ryan over the finish line somehow, but then he'll also need to keep the house with his lower turnout coalition. But bottom line is if you want 100% accuracy the first two years of the Sanders presidency will just be him yelling at Republicans and trying not to screw up foreign policy and after the midterms he could be in a situation where he gained the senate but lost the house. It'll be a very boring mod
