It depends on how gaffe prone McDaniels really is and how strong Childers really is, and I doubt either one is true. Worst case scenario, McDaniels pulls out with the narrowest of margins against Childers after saying something horrifying.
agreed, Ronnie Musgrove was much more popular than Childers, and he was on the ballot in 2008 when it was a strong Dem turnout year (African American voters being a huge part of the Dem base in MS) and he didn't come close to winning against Wicker, so Childers could break 45% but not 50+1
But, Wicker is non-offensive and McDaniel has the potential to be offensive.
