JB's performance, up until the debate, was high quality...
>Steered the country out of the COVID pandemic
>Did better than any other developed country in handling inflation...even used the SPR perfectly to get gas prices under control, and then replenishing the oil at lower cost.
>Produced bipartisan legislation for Infrastructure, CHIPS, etc. that GOP lawmakers were happy to extol in their districts
>Saw record Stock Market growth on his watch.
>Strengthened our foreign alliances in Europe and Asia without having those leaders laughing about a U.S. President behind his back.
>Got our troops...as well as 180,000+ Afghanis who U.S. Vets of that war pleaded with Congress to help...out of Afghanistan...as opposed to DJT's plan to have NONE of them saved...sadly with the loss of 13 U.S. troops to an ISIS-K suicide bomber which was nearly impossible to stop given the low numbers of security troops available.
>Delivered a stirring SOTU speech in early 2024, promising even more progress and productivity.
In short, based on that performance, it was not unreasonable for him to continue serving, until the debate in June. Once that happened, there was no time for any other candidate to mount a full-on campaign...which would require a great deal of fund raising in a very short space of time..., thus making KH the logical choice, since she could get JB's significant $$$. But for a combination of a short campaign, and significant Misogynistic/Race influences, Trump could very easily have lost his 1.5% "Landslide" margin.
btw, the nomination of Kamala Harris broke no rules within the Democratic Party...too bad that the GOP saw no problem in nominating a Convicted Felon, a Rapist, Fraud with an Off-The-Charts Personality Disorder who considers the word of our Worst Enemy (Putin) more trustworthy than all of our Intelligence Agencies. Incredible.
