"That is a can of worms that Mueller didn’t want to open."

John Hinderaker writes at Powerline that the Russians

spent millions of dollars to promote the candidacies of Bernie Sanders, Donald Trump and Jill Stein, and to oppose the candidacies of Hillary Clinton, Ted Cruz and Marco Rubio. So why weren’t they charged with the most pertinent crime they committed? Because Christopher Steele arguably violated the same law. He is a foreign national, and he contributed a “thing of value” to the Hillary Clinton campaign, namely the fake dossier.

Note, too, Section (2): it is a crime to “solicit, accept, or receive” such a contribution from a foreign national. Isn’t that what the Perkins, Coie law firm, the Clinton campaign, the DNC, and probably Hillary herself, did?

…I don’t doubt that election lawyers could come up with defenses for Christopher Steele, were he to be charged with violating §30121. But that is a can of worms that Mueller didn’t want to open. Too many people know the facts behind the Steele dossier, and if he had charged the Russians with meddling in the presidential election under §30121, he soon would have faced questions about why he didn’t indict Steele–and Glenn Simpson, Perkins, Coie, Clinton campaign officials, and perhaps Clinton–for the same offense.It was in order to avoid that pitfall, I suspect, that Mueller overlooked the most relevant federal offense that the Russians committed, and instead charged them with a vague “conspiracy to defraud,” along with wire fraud, bank fraud and identity theft. The first charge is entirely discretionary on Mueller’s part, and Steele didn’t commit wire fraud, bank fraud or identity theft.

I think that is why Mueller chose not to indict the Russians for meddling in a U.S. presidential election.
