I’m waiting for confirmation, but I believe this is a robocall the NRSC is putting out to Democrat households in Pennsylvania. At least, that seems the logical target. If so, it’s brilliant:

Tell me again how no legitimate Democrat will want to run a primary against an opportunistic turncoat, who has opposed the ‘progressive’ agenda for years? (Well, that’s the way they’ll see it, anyway.)

Update: The NRSC confirms that this is their latest robocall to Pennsylvania Democrats. More here.
