I think you've pegged it exactly. There is a time for cautious political calculation and there is a time to trust your instincts. Her instincts are pretty good... /g
Right. I agree.
Tea Party Express had also come through big time for Joe Miller in Alaska, and TPE had invested substantially in CO too. Sarah works closely with TPE, and I think Sarah's endorsement helped TPE's final push for CO: one new TV and radio ad.
Sarah followed-up with her own robo call and several DE Freepers have already received and saved their Sarah robo call.
