McDaniel can have a federal injunction against MS sore loser laws within a week.
There is a place for sore loser laws but not in this case, especially for one of the reasons you state, fraud and also for clear violation of state election law by Cochran and violation of federal election law. MS cannot allow Cochran to stand behind its sore loser laws and a federal court will see to that quickly.
The biggest problem with this avenue is that it is past time for filing to be on the ballot...
But maybe an injunction could be posted on that point as well.
A three way race would be interesting...
