Polls are crap and polls this early are meaningless crap.
Wait till they turn from crap into propaganda and you won’t see results like this. Polls are tools for influencing voter behavior and as for the internals? I could write a spreadsheet macro based on the (RND) function that would produce very realistic but entirely made-up data.
As far as I can tell most polls are manufactured the same way. Sure they may have some people on phones but what assurance is there that that data ever goes into determining what is released to the public? Goebbels and Mao got nothing on them.
Polling outfits are like cake bakers.
Give me the money and you’ll get the cake you want................
