While the previous posters have pointed out a number of problems with this timeline, I'd like to add another: the State governments. Ironically, the very president the Bussiness Plot would have overthrown was the exact same one who by his "Big Government"/Socialist New Deal policies created the agencies and and mechanisms for Washington to impose some level of direct, uniform control over the country. Let's assume this "March on Washington" is successful (For the sake of arguement, its initially pitched as another "Bonus Army" situation like Hoover had to deal with; the Great War veterans coulden't get the previous president to give them their checks early, so they're presenting their plight again to the new one). This time, the picketers are armed and either can overpower any army units sent to disperse them, or McArthur/whoever is in charge of the military can convince them not to fire and instead join the coup. Roosevelt "falls ill", Congress is taken into custody before its members can escape and agrees to write and pass the required laws to implement a Facist state (Democrats and even many Republicans likely doing so at gunpoint. Socialists are also at gunpoint, but get the bullet instead of the ballot), and the local citizens are sufficiently cowed. MacGuire gets on the radio and broadcasts his "Fireside Chat" explaining the circumstances and calls for obedience and order, the Big Red One parades down Washington avenue in their fancy new jackboots, everything looks grand.
Congratulations: you basically have a Facist government controlling the Post Office. No State government is going to recognize the new regime as legitiment, and still have a grip on the majority of the levers of government power. Assuming there weren't enough Senators and Represenatives who escaped to form a "Rump" legislature, I imagine most of the Governors are going to immediately denounce the new junta, mobalize the National Guard to protect themselves, call up local militias and organize them to bolster their ranks, and either call for new snap elections to create a new Legislature at a mutually agreeable and defensible location (St. Louis or Minneapolis come to mind; somewhere on the Mississippi seems likely), or form an "interim government" out of representatives from their state legislatures (with emergency powers delegated to the governors). Without the centeralization of power in Washington Roosevelt's 4 terms created, the coup will very quickly fizzle out as they have no way to martial the resources of the country or implement policy, and the party of Bussiness and the right-wing (I.E.: Republicans) get a knock to their reputation on a national level similar to how the Democrats fell following The American Civil War. Roosevelt is martyered, and the new government (Now with an even larger commanding majority of Democrats) honor his legacy by implementing his programs, which the Supreme Court isen't going to feel safe in opposing as they did IRL.
