Lynch will not prosecute. Obama nominated her because as a black female she gets double-immunity from Republican criticism.
If Hillary gets out of this race it will only be because the Democrat establishment has concluded that she can’t win and they opt to kick her to the curb.
Then of course there is the outside chance that she has a health meltdown. After all, the e-mail investigation and possible prosecution for financial irregularities with the Clinton Family Charities money laundering business must be putting a strain on her already degraded system. I truly expect her to collapse at some time on the campaign trail when she gets confronted with some hard hitting questions such as: "If you lose the election how will you be able to repay the bribes from individuals and foreign governments you solicited in advance?"
