I agree with the general premise of your post.
But T lawyers do have evidence of fraud.
Dead voters represent evidence. And there is more than just that.
The proof of fraud, followed by demonstrating the impact on the election, is what is difficult.
But to your point, election law is largely what these cases are built around. And when you file a lawsuit in a liberal district/state, you expect to lose. SCOTUS remains the goal.
Election law is what must be based on the Constitution, and in theory, the SCOTUS will overturn any state “laws” that are unconstitutional.
Fraud is real. But, a lot of the fraud talk is designed to get people energized behind Trump’s cause.
The idea is that recent changes to election laws opened the door for fraud. The idea of an ineligible voter is easy for the public to digest. But, the arguments in the courts will largely be centered on election law.
