They don't want Roy
The results reflect a divide between the party's economic conservatives, who are lining up behind Riley again now that their hurt feelings over the 2003 Amendment One referendum are passing, and social conservatives, who love Moore. The survey also shows that many party leaders know a Moore nomination probably would fracture the Republican vote enough to put a Democrat in the Governor's Mansion.
There's no guarantee that the GOP rank and file will agree with their leaders' sentiments, of course, but another poll that showed Riley's approval rating almost 20 percentage points higher than Moore's among Republican voters indicates they might.
