Fifteen Republicans offered alternatives to Trump, but the party chose Trump. Both the Republican-controlled House and the Republican-controlled Senate refuse to break with him. There is no doubt that Trump owns the Republican Party, and the Republican Party owns Trump.
But there was still the concept of Conservatism, separate and apart from the Republican Party, as espoused in CPAC. But after this weekend, it's clear that Trump owns Conservatism, and Conservatism owns Trump.
Are there left any Conservatives who will oppose Trump? Romney, perhaps?
Mitt Romney denounced Trump harshly and thoroughly as a "phony" and a "fraud" -- except later when Trump was thought to be considering him for Secretary of State when Romney suddenly had "increasing hope that President-elect Trump is the very man who can lead us to that better future."
Trump owns the Republican Party and, after this weekend, Conservatism itself -- and Conservatism now owns Trump: every thing he says, everything he does, every thing he is.
If you are a Conservative politician or a Conservative voter, Trump is where you are.
