Walmart had an aisle cap well stocked with the Hildabook. Lots of people walking by it without giving it a glance. People do not seem to find her fascinating.
There's maybe a handful of useful idiots left that still think that way.
The rest are either sycophants that see some personal benefit in supporting her - jobs, federal contracts, continued employment/contracts, etc., or those that would see the USA and the rest of the civilized world fall.
Hillary has become entirely political to the point where she no longer says anything that has content. It is hard to be fascinating when you don't say anything.
If Hillary runs for President she will run an entirely negative campaign. She will provide no reasons why she should be President except that she will be the historic first woman President. That will be enough to energize the left.
