That's pretty much what he wanted to begin with. The problem is that he's in an untenable position in the long-term. The GOP base has been fed on conspiracy nonsense (how long ago was the Clinton murder list, or the War on Christmas?) and hatred of the other (Bogative's avatar is a classic example of racism via the Jezebel stereotype - pure slave rape apologism carried up to the current year- and folks like Limbaugh and D'Souza have trafficked in similar junk for decades, never mind Reagan's anti-gay hatred that allowed the HIV pandemic to flourish while he smiled about it), while the elites work to funnel more money to themselves.
Toupee Fiasco just cut through all that and spewed unvarnished white nationalism, starting with birtherism back in 2011. And now the base isn't really satisfied with anything less. McConnell's trying to persuade the folks that thought the GOP was really about "small government" or "good business", but there's just no way to hide the "we hate ******* and queers" faction. But really, this all set up before Moscow Mitch rose to leadership - again, this was set in the Goldwater-Reagan era, and solidified at most a decade ago.
ETA: Gingrich's scorched earth strategy had it's own role to play, of course, but the overall descent to neo-fascism and conspiracy theory wasn't him.
