In just a few hours, we’ll know whether the Tea Party has made Thad CochranWilliam (Thad) Thad CochranBiden has a lot at stake in first debate The Hill's Morning Report — Trump turns the page back to Mueller probe Trump praises Thad Cochran: 'A real senator with incredible values' MORE its latest victim.

The Mississippi senator’s supporters are enthused by higher turnout than was seen in the primary three weeks ago and think he might have some late momentum. But given the trajectory of the race and the heavy outside spending, a Cochran win at this point would be the bigger surprise of the night. 

If challenger Chris McDaniel does win, Republicans could have quite the conundrum on their hands. On Tuesday many state politicians said the wounds would heal — on “The Daily Rundown” GOP Chairman Joe Nosef promised the party would come together and former Senate Majority Leader Trent Lott (R-Miss.) also said “of course” he would support McDaniel if he is the nominee. 

But Democrats were gleeful already about the prospect of a McDaniel win, sending around a memo reminding reporters that fellow Republicans called McDaniel “ 'Dangerous,' 'Extreme,' Someone Who Associates With “White Nationalists & Segregationists' ” and even NRSC leadership had called his campaign “ 'Despicable,' 'Extreme' and 'Revolting.' ”

National Republicans took a real risk in the fervor with which they railed against McDaniel, and whether they admit it or not, they’re praying their words don’t come back to bite them. 

Even in other races where incumbents or front-runners were upset and Democrats subsequently won in November — like the Indiana contest in 2012 or Nevada, Delaware and Colorado in 2010 — the vitriol between the two candidates was nothing like this race. And that’s exactly why Senate Democrats are feeling optimistic about former Rep. Travis Childers (D). A win in the Deep South is still a long haul, but after tonight Democrats could finally have the “Todd Akin” of the cycle they’ve been looking for to drag down other candidates.
