My response was more so to the “you don’t get to ‘wish’” part. It could go the same way, it could not. It’s not consistent year to year. Assuming it is when long term data does not support that, isn’t helpful

Over the long term, there is no meaningful partisan statistical bias in polling. All the polls in our data set combine for a weighted average statistical bias of 0.3 points toward Democrats. Individual election cycles can have more significant biases — and, importantly, it usually runs in the same direction for every office — but there is no pattern from year to year
