Simple.
The RNC and the rest of the GOP "Leadership" are criminally incompetent country club sons of bitches who are afraid of being branded with the "McCartyism" tag.
The most successful element of the communists propaganda campaign over the last 50 years has been to terrify right wing politicians with threat of being accused of "McCarthyism"
Its high time that communists are exposed and not allowed to hide under "Liberal" and "Progressive" labels.
These cockroaches in Congress and the media will scurry back into hiding once the lights are turned on.
Unrelenting attacks on the enemy within, in the form of prosecutions of the corrupt members (that would be about 95% of them) of the "Congressional Progressive Caucus", would be a good start, the leftist media is already mortally wounded, just need to be openly attacked as com symps by Palin or similar to be finished off for good.
Make the reds understand that their bullshit will no longer be tolerated, they will NOT be stealing any more of the productive class via the electoral process, and if they want a socialist revolution, they had better be prepared to do it the old fashioned way, at gunpoint.
