Were they voting for President? No. They were voting for a Senator of their state. The only citizens that would be affected were those of that state. Not a SCOTUS issue. Just one more reason to overturn the 17th Amendment
The times, places and manner of holding elections for Senators and Representatives, shall be prescribed in each state by the legislature thereof; but the Congress may at any time by law make or alter such regulations, except as to the places of choosing Senators. (emphasis added)
Sure sounds like Congress would trump the state legislature. Of course, since the state judiciary has just been given a role not given to it by either the Constitution or the bodies that the Constitution gave this role to, what good is the Constitution?
Then unless you're from South Dakota, I don't expect to hear any complaints from you about how Daschel is affecting you.
