I don't disagree with your central premise.  When, in 2012, the GOP sold out to the right-wing, their party values shifted far to the right...including, as you mention, support for racism, xenophobia, homophobia, misogyny and hard-core anti-intellectalism combined with the control of a wealthy elite and populist followers....indeed, a strange creature.  That "new" GOP is not falling apart as the more reasonable faction says "hey, this isn't what we really want."  Who know what will transpire after Nov. 8th, but we do know it will involve some radical changes or the Party is dead.
