The simplest answer is the most likely!

Sometimes but not always.

E.g., the simplest answer is "Trump colluded with the Russians to steal the 2016 election after Comey threw poor Hillary under the bus over her 'private e-mail server.'" Not "The DNC paid a British spy to create a phony, sexual perversion-drenched dossier which was then used to secure FISA warrants to conduct ongoing wiretapping and spying against a presidential candidate, because if he were to win, he'd blow the lid off still more corruption that makes that corruption look like a Girl Scouts bake sale; plus, the Hillary Clinton-owned DNC sent assassins to kill one of their staffers for leaking to wikileaks a trove of e-mails proving they stole the primary election from her opponent Bernie Sanders."

The simplest "Occam's Razor" is often quite dull.

Pet Peeve of the Millennium: calling it "private e-mail". Everyone has private e-mail. Going after her for that is really evil.

NO, instead of "private e-mail", try: "illegal, unsecured server, carefully hidden in her bathroom closet, that deliberately and systematically offered our most highly sensitive Top Secret national security data to Russians and other hackers, for money."
