Wildcard berths that can't beat teams without a winning record should have homefield advantage
I'm listening to "double down" right now on audiobook. In many ways it seems Carson is pretty similar to Huckabee in 08, only with less oratorical skill and political credentials.
Both had rabid, passionate evangelical fanbases, despite the party not taking them seriously as contenders. Huckabee's support though as it turns out was extremely regional- he was a serious contender in the bible belt and caused establishment candidates no shortage of problems, but was an also-ran and noncompetitive everywhere else.
I suspect Carson's support is similar.
Keep in mind, though, that the feelings of the base were incredibly different back in 2008.
