Hi,
You had asked for information re: the Mississippi Strategy:
I don't see any evidence, however, that Ted Cruz is participating in accusations of racism, which is the central acccusation about the implementation of the strategy against Trump.
Calling in 'Rats against McDaniel to support Thad Cochran is about as low as it gets, just offhand, but the speaker of the Texas house of representatives does it every day and has done so for 10 long years now. He isn't missing any sleep, either.
