In 2010, the then conservative Canadian-American commentator David Frum feared that the conservative Tea Party movement would radicalize the Republican party, which would bring it short-term gain but long-term loss. Two years later, after some unconventional Tea Party candidates had defeated establishment “Republicans in name only” in primaries to then lose in the general elections – like Christine “I’m not a witch” O’Donnell in Delaware or Richard “God intended your rape child” Mourdock in Indiana – the Republican establishment successfully blamed the Tea Party movement for the party’s electoral defeats and regained control, albeit, as it turned out in 2015, for just a few years.
Recently, some commentators have argued that radical outsiders once again endanger Republican success in the midterms. While this might be the case, don’t expect this to seriously change the far-right direction of the party.
