US Supreme Court has limited jurisdiction over election matters which are governed by state law and state courts. Trump is barking up the wrong tree ... another piece of fake news. In Bush v Gore, US Supreme court denied a recount under equal protection clause, which is a different matter entirely than what Trump is attempting to do ... shutdown the counting of legally submitted votes.
The election is running closer than I expected. Biden still looks likely to prevail, but clearly there is a large body of the US population that either have no values, suspend those values when it comes to Trump, or who literally struggle to see the difference between shit and shinola. It's disheartening.
Trump is not a political argument but a values argument. Trump is not a political animal, cares nothing for politics, could not explain a political ideology if a gun was pointed at his head. He is a person with no meaningful value system. It's all about self and screw everybody but him ... even his wife(s) and kids. You either believe it is acceptable to lie every day, multiple times a day or you do not -- that is not a political issue, but a values issue. You either believe it is acceptable to deliver massive abuse and cruelty on children and families at border detention centers or you do not -- that is not a political issue, but a values issue. You either believe it is acceptable to ignore bounties placed on your military personnel by foreign powers or you do not -- that is not a political issue, but a values issue. You either believe it is acceptable for a leader in government to commit massive fraud or you do not -- that is not a political issue, but a values issue. And so on. The list is practically endless.
It is not possible to have a political debate or discussion with somebody when their value system is a void. You can't get past the humanity element of the situation. A person's political view points can wax and wane, but their values are at the core of who they are as a person. When you have no values, you cease to have humanity.
