The disconnect is that the mainstream, liberal punditry has equated "moderation" in Republican politics with "sounding nice." Liz Cheney, John Boehner, Marco Rubio and Mitt Romney (among other Sunday morning mainstays) are not moderates in any *ideologicial* sense of the word, but only in that they converse and transact in the preferred euphemisms and tautologies of Democrat-run media. The policies and philosophies they've championed throughout their careers are decidedly more conservative than anything offered by Trump or Trumpism.
Just cause Trump was more protectionist than Romney didnt make Romney more conservative than Trump lol. Trump was far more conservative than Romney when it came to things such as the minimum wage, healthcare(remember Romney came up with Obamacare), Trump cut corporate taxes more than Romney proposed and probably to the right of Romney on regulatory policy .
Also no way in hell was Bush more moderate than the guy who wanted to do strict campaign finance reform , voted against Bush's tax cuts , supported cap and trade etc
