The CBS poll was an online poll; The CNBC was twitter poll, and the CNN/AP polls were polls of RV.
Those online polls are a joke, as we all know.. DU, DB, and Kos, etc, were all pushing CBS and others to do what they could to pound those polls early and often, even linking ways to vote multiple times..
Throw out the two online polls they are a completely crap and are nothing but people hitting the polls voting over and over again with no control. They even have websites that refresh for you on those online polls to keep voting for you. They’re garbage but of course Politico needed one to give to Biden and had the use the CBS one.
The only one that was a real poll was the CNN/AP one even though it had a MOE of 5%
