Why?
If she gets the nomination, and is then indicted, she’ll keep on running.
Her chances of winning the election may actually go up.
Then, if she wins the Presidency, her victory will throw the entire system of American jurisprudence into a cocked hat. She’ll get to re-define pretty much every federal law from scratch.
This would be delightful to Hillary, and her supporters.
I predict that her presidency will be the most corrupt ever seen, up to and including murder. Yes, I said that.
Justice will probably not do anything until after the election, and then Obama will quietly pardon her right after the election, before she gets indicted, is my guess.
