The fact is fraud or not, Biden is the president. The GOP will not stick their neck out for Trump because they know what is coming. They will sweep both senate runoffs in GA and once you add in Manchin, you have a 53 votes against any hard left policy. The will play to win the house in 2022 which historically they probably will.
I expect both parties will enjoy the ability to do nothing and scream it’s not their fault because the other side is obstructing, while passing several large spending bills. The conservative SC will likely strike down any hard left executive orders Biden puts out despite the unlikely nature he does. The economy will probably take off and probably have several good years due to this fact of no change.
Then here comes 2024.
