Yes they can, just as so many believed Harris would win because their algorithm provided them a reality where that was a certainty.

Not many believed she was going to win near election time, so Im not really sure what you're talking about. Many companies clearly started to pivot. Of course some believed one way or another but "believed" is doing heavy lifting there to imply iron clad irrational belief as oppsoed to simply thinking something is more likely than something else.

Its also a complete distraction from the point as you give no further reasoning for saying that they can, and just appear to try to shoehorn in a "both sides" message where it doesn't even make sense.

What’s dumb is to expect people to vote Democrat when the cost of living rose so sharply under Biden

This is delusional thinking. Its like thinking the president directly controls the price of oil. Costs were rising in many places. People must be evaluated via what they do vs the baseline.

and his handpicked successor said publicly she wouldn’t do anything to change it.

This also isnt true at all. Its basically conservative/conservative adjacent (aka reddit """communists""" whose communism purely consists of supporting the worst availible options because they don't have their idealist option) talking points pretending she didn't have any policies, when she did in fact have a lot of them.
