Let’s also look at the effect you dropping out would have on the frontrunner, Donald Trump. If you leave the race, it would allow the anti-Trump wing of the party to rally around someone else while also depriving Trump of his most reliable punch line, which is of course your candidacy. Given that Trump winning the nomination could foreseeably lead to the dissolution of the Republican Party, it would be a great act of loyalty if you were to cut him down by ending your campaign.
And that’s the story you can tell if you get out soon, Jeb. Your exit could be portrayed as a strategic retreat in a larger war for the GOP. You were the adult, you put ambition aside and saved your country and your party from Donald Trump. For the rest of your life, people will come up to you and tell you that you were the best president this country never had. You’ll be the premier elder statesman of the GOP, the man who retired gracefully instead of going through the expense of losing ugly.
Plus, you will have saved this country from the disheartening spectacle of another Bush vs. Clinton race. Nobody in America wants to see that weirdo dynastic power struggle play out. We’ll all appreciate you for not putting us through that.
