Senior political reporter Aaron Blake, who writes The Post’s new newsletter by the same name, and senior national political correspondent Ashley Parker sit down with Martine Powers to discuss the expectations for this weekend’s South Carolina Republican presidential primary, the chatter on who is on former president Donald Trump’s list of potential running mates and the latest in the Republican House-led impeachment inquiry of President Biden. Subscribe to Aaron’s newsletter, The Campaign Moment, here. Subscribe to The Washington Post here.Today’s show was produced and mixed by Ted Muldoon.
