Maybe not the only way, but clearly her optimum strategy. Question is, how would she do that?
Well, this is what is motivating her immigration talk.
No real Conservative or Republican is going to take her seriously. I don't believe she'd enforce law anymore than another would on this issue. I don't believe she even thinks she'll win many Conserves/Reps with this pretension.
The idea is to keep a sensitive issue with Reps on the front burner. To keep the tension building and then press the right emotional button during the election so that we'll split.
