Will Trump destroy the Republican Party?
Nope. Trump is much too mediocre to yield anything approaching that level of power.
It is the Republican Party that is destroying itself, albeit in a painfully slow agony.
If he does, I think the destruction will most likely take the form of a split in the Party that leaves both parts too much in the minority to win most elections. What do you think? Will Trump destroy the Republican Party?
It seems to me that both voters and politicians that have any sympathy for the Republican Party have been much too scared of that possibility to allow it to happen. While that is certainly the direction things are going towards right now, I don't expect that last.
If Republicans had any significant defenses against the Sunk Cost Fallacy, Trump would not have been elected to begin with. Because they do not, they will just keep damaging America time and again until the pain becomes too crippling to ignore. A few will of course learn better during those painful decades, but the Party would not have survived to this day in its present form if it had any ability to learn better.
What I am hoping for is a significant backlash against the
de facto bipartidarism, spurred by the realization that even for those most passionately opposed to the Democrats there are no good news to be found in the Republicans. GWB got excused on the grounds of "national security needs", and Obama was an excuse since then. No longer.
It would not surprise me to see the emergence of some form of third choice, largely (and gradually) built of the remains of the Republicans as it becomes increasingly harder to maintain their current narrative of victimism.
