From George will at National Review, Donald Trump’s ‘peak’ Might Be Coming:
If Trump does become acquainted with gravity — no, not intellectual sobriety; nature’s downward tug — it will be for two reasons: The Republican party, which together with the Democratic party has framed the nation’s political debate since first running a presidential candidate 160 years ago, is not a flimsy dinghy to be effortlessly commandeered by pirates hostile to its purposes. And the lavish media exposure that has fertilized the growth of the weed of Trumpism in the garden of conservatism might still stunt its growth by causing his supporters to have second, or perhaps first, thoughts. A steady diet of his self-adulation can be cloying; even an entertaining boor can become a bore.
Mitt Romney’s denunciations and ridicules, reciprocating Trump’s, are not designed to dissuade Trump voters. It is axiomatic that you cannot reason a person out of a position that the person has not been reasoned into. The adhesive that binds Trumpkins to their messiah can be dissolved by neither facts nor eloquence. Romney and other defenders of Republican traditions are trying to prevent a stampede to Trump of “Vichy Republicans,” collaborationists coming to terms with the occupation of their party.
