Updated my bot, now has a 85%+ win percentage. And I renamed it since the kill method is rather different, so it's no longer called Republican Bee 2.
The big difference which really helped it beat spinner was the line "128 .badarea store". Beforehand it just wasn't spreading fast enough to infect all the spinners.
