And yet the 538 NC number is right where it would be if the only polls considered were the most Marist, Morning Consult, and NYT/Sienna polls.
If the goal of this “flooding” is to impact that number, to skew the polling “average” then it is doing a very poor job of it. (RCP possibly the exception as they seem to actually do averages, rather than aggregate with any sophistication. But even they are only impacted slightly.)
Yes, there are people on each side who will glom on to the poll that tells a story - one that panics them or one that sells clicks or one that might drive excitement and funding because suddenly it is close! (A single poll.)
Sure just as your silo is sure that there is rightward skewing going on, the other silo only reads the polls they like. They may think Trump is doing better than the aggregate results would say. And he may be. If these rightward polls are supposed to drive fundraising though, they have failed there too. Trump’s fundraising is way down compared to past cycles and compared to Harris, including in small donation percentage.
Will those in that silo be more likely to believe a Trump stolen election lie because the polls they saw said he was going to win? Nah. They would believe it no matter what polling had been saying, Trump said it, they “heard” the polls were skewed to Harris, the fix was in, whatever.
That Washington state bit was from a poll on March??? All I can say is that Ferguson has been ahead in every poll listed on 538 since. So not very effective flooding. And a lightly polled race line that one would be the easiest sort to impact.
