This week, the FiveThirtyEight Politics podcast discusses whether the Nunes memo was much ado about nothing — and even if is is, whether it could still cause political consequences. The crew also discusses whether Trump has molded the GOP in his image and what it takes to shift a party’s ideology — and the ideology of its voters.
