Even from a pragmatic perspective, the changing-horses-midstream strategy doesn't make sense. Whether or not Harris is capable (and can find *her* potential VP in time), it conveys a lack of confidence, and would just be pounced upon by outlets and the Republicans.
Republicans & bad faith media are going to attack the Democrats regardless of what happens. Harris will of course be subjected to all the same slime and nonsense Biden is. Switching is a drastic measure, not taken lightly, but Biden's ability to campaign is seriously diminished. Desperate times.
i agree, though i'll note that biden dropping out of the campaign and dropping out of the presidency are two different things, and i think the latter is absolutely insane and am absolutely not recommending that.
