the trump team has lost every lawsuit thus far (and they didn't even really lose-the cases were basically dismissed immediately, like Mike Tyson declining to fight a 3 year old), they've provided absolutely no evidence of any widespread fraud, and this current filing in front of the supreme court is filled with misrepresentations, incorrect statements of law, and nonsensical ramblings...
but yeah, he's got a chance to win. just like a middle school football team would technically have a chance to win in a game against the New Orleans Saints.
