Liberals won't buy it. They hate Bolton. This is a book for conservative hardcores, and they will not buy it if there is a single aspersion against their Trump.

Poor old WH dictator wannabe has worked so hard to control everything with lies and EOs and NDAs and threats and tweets and...now finds out that's just not enough. So sad.
