You're kidding yourself. The higher quality polls are as accurate as one can expect polls to be. Even in a perfect situation if you estimate a proportion with a random sample of 1000 people the "margin of error" is about 3 percentage points and that's for the percentage one candidate is going to get. If you're talking about the difference between candidates it's about double that.css75 wrote:
As we have learned from elections polls are not very accurate. People will lie to the pollsters especially conservatives, so they don’t have to hear lib vitriol.

If you look at the overall popular vote for either the 2016 Presidential Election or the 2018 overall House vote the average of the differences for all the polls were very close to the actual differences. And when you look at the individual polls there was only ONE case among the two elections where the actual result for the difference between the candidates or parties fell outside of the margin of error for any individual poll reported at the RealClearPoliitics site. And that one case was the Rasmussen poll saying Republicans were going to win the overall popular vote in the 2018 House elections by 1 percentage point right before they lost it by 8.4 percentage points.
