/-----/ You mean like Rasmussen who is the only polling company that still conducts weekly polls, using the same methodology? You mean like that?/----/ Uhhh, three groups were sampled Repubs, Dims, and Indies. That makes it 33% each not 50/50.Why do Conservatives struggle so much with Statistical Sampling Theory? I realize it is more advanced mathematics than the arithmetic Conservatives are limited to, but it is not really that hard./——/ Only 818 sampled out of 7,000,000 NC voters is .00011%, a meaningless sample, plus an over sampling of democRATs. It was a poll to create a news story and help Dem democRATs raise money. Show me a poll of 1,500 likely voters with those results, then I’ll worry. What confuses you?What looks fake?/——/ Another fake poll of 818. From your link after a lot of digging:Almost always siding with the wishes of toxic President Donald "Mr. Make Matters Worse" Trump sure isn't helping Tillis:

New NBC/Marist poll offers more encouraging news for Biden and Cunningham • NC Newsline
2020 election; NBC News/Marist poll shows Joe Biden and Cal Cunningham running well-ahead of Donald Trump and Thom Tillispulse.ncpolicywatch.org
In the Presidential race Joe Biden leads Donald Trump 50-46, up from a 48-46 spread a couple weeks ago. So they found 407 who hate Trump and they had to over sample democRATs.
PPP interviewed 818 North Carolina voters on July 7th and 8th. The margin of error is +/-3.4%. Full results here:
If you are a Democrat, press 1. If a Republican, press 2. If an independent, press 3.
Democrat ........................................................ 38%
Republican ...................................................... 32%
Independent .................................................... 30%
Q8 If you are white, press 1.
If African-American,
press 2. If White............73%
African-American ............................................ 21%
Other..........................................6%
Each poll has a margin of error based on the sample size. That margin will show the range the poll falls in.
Polls are conducted randomly. A poll structured to give you 50 percent Dems and 50 percent RepubliKlans will give you a 50/50 result. It is the Independents who will swing the election
I used to buy into these polls. Then I started studying the methodology closely and learned a great deal. A poll is a snapshot, not a forecast. You should try it: How can a poll of only 1,004 Americans represent 260 million people with only a 3 percent margin of error?
"The margin of error depends inversely on the square root of the sample size. That is, a sample of 250 will give you a 6 percent margin of error and a sample size of 100 will give you a 10 percent margin of error. A 10 percent margin of error is not so useful. It would give you vague claims such as, "The proportion of Americans who support the death penalty is somewhere between 60 percent and 80 percent." Pollsters thus spend the money to get a reasonably large sample. In the other direction, by surveying 4,000 people, you can get the margin of error down to 1.5 percent. This sounds appealingly precise (for example, "The proportion is between 68.5 percent and 71.5 percent"), but it is generally a waste of time because public opinion varies enough from day to day that it is meaningless to attempt too precise an estimate. Indeed, to do so would be like getting on a scale in the morning and measuring your weight as 173.26 pounds."
You also ignore the cumulative accuracy of polls.
If polls show Dems lead by 5 percent one week and Republicans lead by 4 percent the next and there is no consistency, you have little confidence in the results.
However, if week after week, poll after poll show the same results, you have confidence in the accuracy of the results

What They Told Us: Reviewing Last Weekâs Key Polls
In surveys last week, this is what America told Rasmussen Reports...www.rasmussenreports.com
In surveys last week, this is what America told Rasmussen Reports:
- President Trump ended the polling week with a daily job approval of 49%.
Rasmussen has his approval at 45% today. There is no way it is mov9ing up and down they way Rasmussen suggests it is.
