This woman went into robocall mode. You could have started speaking Spanish and you'd have gotten the same response.
She has a script, she's given latitude time-wise -- listening to you do a check-off list (a mostly good one, mind you) merely delays having to make the next call.
In campaign calling, you get into that third hour and dread sets in, because people interrupted from watching The Voice or smoking a doobie or whatever, go straight into douchebag mode. Since you weren't being a douche, she was content enough to glaze over and let you run with it.
And on to the next call.
Some time ago, I received a different Obama campaign phone call from someone who readily agreed with me that Obama had done all of things that I had said he had done. This earlier caller was clearly thinking for herself, and was not in “robocall” mode. She admitted to having reservations about Obama, but thought that he was better than Romney. Not all of these callers are mindless idiots.
