This is likely the result of putting a thumb on the scale of a neural network driven system. They want to boost her, so they just up the weights on nodes that respond to "Kamala Harris". They're hoping to get a seamless, undetectable increase in results, but what they don't realize is that closely adjacent queries are going to be effected more strongly than the generic queries.

The killer app for AI is generating bullshit and lies, and we're seeing it in action right here. They'll probably learn from this and refine their lie machine even more.
