I usually see innuendo everywhere but I have to admit I didn't, and still don't, see it in this. I thought the "heart-melting" comment was designedly contemptuous, perhaps implying a too-emotional response (and if she does make an ally of a hard-line natural opponent like him over one atypical issue, I don't think she's thinking very clearly either. The first thing he'd do in power is cut her funding, I suspect.)

But it never entered my head that the remark might be implying any romantic connection. until she mentioned the possibility. Since then, of course, I have been speculating wildly...
