If they ARE building a real case against Hillary or any of her counterparts, they will have evidence so overwhelming that it will be a race to courthouse to see who gets the best deals. Would I be surprised it all gets swept under the rug? No. However, in my experience, the feds (FBI, IRS-CI, US Attys) simply don't mess around with stuff unless they are 1) extremely serious about it, and 2) have enough evidence to basically guarantee pleas and convictions.
Interesting. Thanks.
