senator wicker was all for this and supported thad’s efforts to enlist democrats complete with 175 thousand Republican National Senatorial Committee dollars to cover the walking around money and the robo-calls and flyers calling Senator McDaniel a racist, and a klansman. senator wicker’s office said he was proud of the RNSC’s effort in senator Cochran’s behalf and that enlisting democrats to vote in the republican primary was a good strategy he supported. He may well need a bunch of them in his next primary.
