Meanwhile, I try to gather info.
For example, you might see my replies 59, 60, 61, and 62 at Kari Lake’s attorney: Evidence of rushed ballot verification warrants overturning 2022 election
Also, I am working up a list of the number of actual registered voters per state. This work requires online visits to the Secretary of State office for each state.
Otherwise, the statistics used by the media, by government, and many other organizations, are estimates based upon estimated information that is gathered by the U.S. Census. I'd qualify that, by saying, that a few organizations such as Judicial Watch and Heritage Foundation, probably have some reliable numbers/stats.
Some states offices have the information. Arkansas information is difficult to find, and they might do that on purpose. Because academics, the liberal media, and some organizations will use voter stats against a state - re the usual hammering: "chilling effect" and other slings and mud tossed from the left.
Correction:
Trump does NOT seem to have an out-of-office administration for addressing various errors on his part.
