This is my point. You explained it. Corrupt pollsters
This is, I think what longroom was trying to say before he was mysteriously silenced. I use Gallup as my backup and compare their numbers to these other pollsters. No secret forula sauce. At some point, if it hasn’t already started, I expect some of these folks to start to make up stuff as they go along, if the surveys do match the narrative. Being a Democrat means never having to tell the truth.
