Patrick Buchanan offers some insights on the Rule-or-Ruin Republicans here:
The Republicans are committing a protracted political suicide, and the nihilists, who purged the remaining Conservative rationalists from the Party, are stage managing this spectacle. The dithering of the now Closeted Randian Paul Ryan is indicative of this political melodrama.
After this ends, in the defeat of Trump by Clinton, (So goes the narrative constructed by respectable pundits.) will the Eisenhower Republicans reassert control of the Party? Or will a Conservative Party be born out the defeat of the nihilists, who control the levers of power? Then there is the burning question: can the political career of Paul Ryan be redeemed?
