As noted yesterday, Texas is leaning on Bush v. Gore.
Today, Team Trump added its voice:
The violations of state election law, which is the “manner” the Legislatures of the States have established for choosing presidential electors, violates the Electors Clause of the U.S. Constitution and thus this matter arises under federal law. See Bush v Gore, 531 U.S. 98, 113 (2000) (“significant departure from the legislative scheme for appointing Presidential electors presents a federal constitutional question”) (Rehnquist, C.J., concurring).
Team Trump also says the following:
Moreover, as explained more fully in the complaint filed by Texas, the number of ballots affected by illegal conduct of state elections officials greatly exceeds the current margin between Plaintiff in Intervention and his opponent in the election for the Office of President in each of the respective Defendant States, and the four Defendant States collectively have a sufficient number of electoral votes to affect the result of the vote in the Electoral College for the Office of President. Proposed Plaintiff in Intervention therefore clearly has a stake in the outcome of this litigation.
