What's the time frame on securing these elections?

By 2022.

As it stands, they have solidified things like mail-in voting, and yet there is no legislation in any of those states to remove that, as far as I know.

AZ, GA, PA, NH, WI and MI have legislation: Scott Presler is tracking it, I urge you look at his work. Rand Paul is also going to the legislatures and lobbying them. Mail in voting was also, mostly, applied temporarily for this election in those states.

Also, what about the judges who ignored any cases, and sat them aside during the last election. How do you plan to deal with them? What about the supreme courts of those states when they decide against the legislation that may have actually passed in said states?

Courts don't get involved in election cases after the election, or at least it's highly unlikely which is what we saw. Robert Barnes is working with the courts, and a court in Virginia has already declared mail in voting to be illegal and barred it from being used next time.

Also, for Nevada, and other states, there are laws that allow illegal voting, how do you propose removing those laws? The first one involves illegals getting ID cards, and the second one involves registering voters when renewing, or applying for ID'S?

Nevada is an uphill battle, since we don't have a Republican legislature. My goal is to first get rid of electronic voting machines, which is a big enough win.
