I understand that this is what most people would think but you need to remember that this is the constitution. To change the constitution you need much more than a legal battle. You need an amendment. To do that you would have to have this.
The Constitution provides that an amendment may be proposed either by the Congress with a two-thirds majority vote in both the House of Representatives and the Senate or by a constitutional convention called for by two-thirds of the State legislatures. None of the 27 amendments to the Constitution have been proposed by constitutional convention. The Congress proposes an amendment in the form of a joint resolution.
That can be drug out for the rest of the four years easily if mixed with a court case. It has to be something else.
