They do it RCP it every time. Quickly try and cover up any evidence of their crimes at the last minute that is, by rapidly changing their polls to reflect reality. That way, they can always claim their polls were right or within the margin of error all along .

So if you average 10 fake polls together you get a good poll?

RCP doesn’t do anything more than arithmetic. They take all the poll results for a particular state and compute an average result from them. The races they are “changing” are the no tossup ones. This occurs when new polls change the average result from favoring one candidate to another. Their other map, with toss ups, gives a better idea of what the polls are saying about the race. The no tossup map is misleading.

For example if there are 5 polls in a state with results of Biden +1, +2, +1, and Trump +2 and +1, the average would be Biden +0.2. Obviously it’s a tossup. Suppose that the poll that had Biden +2 issues a new result showing the race tied. The new average would be Trump +0.2 — that’s a change on the no tossup map, but it’s obviously not a real change in the actual status of the race; it’s still a tossup.
