"Palin is killing it for him ..."

I am talking to a woman in a dank apartment building. She tells me that she is undecided.
I ask her if there is anything in particular holding her back, one way or the other.
She says no. She just needs to think about it.
And then she says, "Palin is killing it for him, if you know what I mean." A bit of a grin plays on her lips. Mischievous. Shy. An admission. We shake hands, I thank her and am on my way.
