Certainly, Bob Riley should be expected to secure more endorsements than challenger Roy Moore due to Riley's incumbency factor and his extensive GOP establishment ties. But Moore's followers are nothing if not loyal and most Republican politicians won't wish to antagonize them.
So I think it will be interesting to see which politicians go on record in favor of one candidate or the other. I was able to pick out a few endorsements from some of the coverage following each candidate's announcement. And an article in D.C. mag Rollcall (subscription required) felt out the AL delegation on the governor's race.
But I am sure the current list has only a fraction of the endorsements to come. So if you see a reference to an endorsement of either Riley or Moore by a politician, opinion leader, or anyone of influence let me know. If possible attach a link with some verification of the endorsement, but that might not be available in all circumstances.
So take a look at the first unveiling of the Endorsement Watch and keep your eyes out for more to add!
