First, the federal lawsuit proceeds on its separate merits (an act of Congress regulating federal elections). By federal law, access must be granted.
Second, if the state won’t allow access except upon onerous cost and time-consuming delays, then the appeal to the state courts should proceed based on the evidence in hand and projections where access has been disallowed.
Third, as the U.S. Senate is the final judge of its members, Tea Partiers should inquires of candidates for the Senate throughout the country what standard they will have for accepting a Senator from Mississippi.
Agree with your first point. And I am hoping that the time tolling on the 12 day window to file a legal challenge is stopped by and reset by the federal court.
Your second point is worthy but it weakens the case immensely to not have the complete canvas.
Your third point is nuanced and will not be realized because most of the GOP Senators in Congress are under the thumb of McConnell.
Are you speaking of the lawsuit that has been reported as having been filed by True the Vote? What is the reason that it claims that they have standing? Do you have a citation to the federal law that you mention?
