Just look at the current issue being discussed in the media, the issue of the DNC 'rigging' the primary. In fact: 1) She did not bring this up so was not seeking this attention. 2) what she did is not illegal; it's a political move. 3) She is not the one causing all these issues to come up in the media. 4) She may be writing a book, but many, many public people do that: it is nothing unusual. 5) She's a private citizen now; she has the right to speak out on any issue just like anyone else.
It's not an issue of her 'not going away;' it's an issue of her being stalked by the media and her opponents. Trump brings her up regularly, more than anyone else. He is responsible for most of the attention being paid to her.
