The red wave did not materialize because establishment Pubbies refused to support Trump. He put it the effort. They did not. It really is that simple. One man cannot do it alone. It takes an organization to fight an enemy that is deeply and broadly organized.
Trump is going to have to rebuild the Republican party from the ground up. No one else is capable of doing it. There are some excellent Lieutenants but they require a general.
Trash burns easily. A good plan.
My suggestion is that DeSantis, rather than running for President, serve out his term as Florida governor, while using his influence to reform the party at a National level. As it stands, the National GOP is just too much of a dumpster fire, and it won’t be fixed in time for 2024.
