The Mississippi Republican Party has responded to the McDaniel campaign in the form of a statement to the public and a letter to Chris McDaniel's attorney, Mitch Tyner, from Joe Nosef, MS GOP chairman. (Here's the letter in https://www.dropbox.com/s/xfc6a18ax1k2vr8/Chairman%20Nosef%27s%20Letter%20to%20Mitch%20Tyner.pdf">PDF format.)
The upshot is that the MS GOP is suggesting to Tyner that they go ahead and take their fight to court, in part because the MS GOP's executive committee would only have 24 hours starting Aug 13th (once the requisite seven days notice for a meeting was circulated) to figure out whether it makes sense to overturn a U.S. Senate primary result. That's just one day before McDaniel would be forced by law to go to court on Aug 14th.
So, they're punting. (Which sometimes makes sense on Fourth and Forever.)
Jackson, MS. –– Joe Nosef, Chairman of the Mississippi Republican Party, issued the following statement today regarding a challenge to the results of the June 24th primary runoff and a letter sent today by Chairman Nosef to Mitch Tyner, lawyer for the Chris McDaniel campaign:
"Our 52-member volunteer Republican State Executive Committee has been asked to spend just five hours listening to legal arguments and then overturn a United States Senate primary in which over 360,000 Mississippians cast votes.
It is neither prudent nor possible in a single day for any political committee to process and review the significant amount of complex evidence necessary to make such a decision, and attempting to do so would be prejudicial to both candidates.
Under these circumstances, the only way to ensure that the integrity of the Mississippi Republican Party and our election process remains intact is to have a proper, public review of this matter through the judicial system in a court of law. Both candidates have said they look forward to such a review, and now is the time. "
