Robert Mercer and the rest of his comic book villain clan have been awfully quiet

They are generally recluses, so being quiet is not too surprising, but they had their moment where they were very loud. The family also likes poker, so keeping their cards close to the vest is also not surprising, but they have fallen off the earth...I hope it is their lawyers telling them to STFU or they could be next (if they are not already in Mueller's crosshairs).

Or it could be that Jim Simons told Mercer to STFU and stripped him of the CEO role at Renaissance because he was causing trouble and other top scientists did not want to be recruited to the fund due to Mercer's politics.
