using polling averages as a better indicator of how candidates were performing with the electorate.

to use polling averages rather individual polls. In theory, the average of all polls will smooth out the inherent biases of the data. For ex, a D leaning poll universe would cancel an R leaning poll universe. It works as long as the pollsters are credible and follow best polling practices. But since the polling averaging sites just add in each new poll with no scrutiny, if there are a lot of polls designed to be deliberately biased toward Rs, then the polling average will be
skewed.

That's what the Rs did in 2022, flooded the poll aggregator sites giving the illusion that Rs were going to win many seats in Congress. The same thing is happening now.
