Cross-posting to a great article at NR by Andrew McCarthy. If the gOpE hopes to have a "brand" at all, they better listen to this ...
When the NRSC had to beg Cruz not to endorse anybody primarying a sitting Senator, in addition to his work with DeMint, it was obvious they feared and hated him, especially John Cornyn and Thad Cochran.
The House now has a replacement Repub Study Cmte, and I suspect the Senate will have the same, if only informally.
