Democratic Primaries
Related: About this forumReuters/Ipsos did 2 different GE polls Dec. 18-19, two different sets of voters.
They got two different results.
One of the polls has a higher percentage of Republicans than the other poll has. That's the poll Sanders is doing better in, the poll that a Newsweek article is hyping, and that a couple of DUers who can't stand Biden posted, 45 minutes apart.
This is the poll where Sanders beats Biden by 2 points, while Biden beats Trump by 1 point, and Warren loses to Trump by 2 points:

In the other Reuters/Ipsos poll also conducted Dec 18-19, the numbers of respondents and their political affiliation were different:

In that poll of Democratic candidates versus Trump, Biden and Sanders both beat Trump by 4 points, Warren beat Trump by 2 points, Bloomberg beat Trump by 1 points, and Buttigieg lost to Trump by 1 point.
Don't ask me why they did two separate polls this way.
They messed up the math they're reporting, too. In the first poll there, the one with nearly as many Republican as Democrats (which is wrong for a GE poll), their internal table at the top of the press release says the respondents were 43% Democrat and 38% Republican. Nope. Takes seconds with a calculator to check that and see both parties are 40% (well, the Republicans were 39.6%).
Anyway, their polling is messed up.
And the poll that's most messed up is the one showing Sanders doing slightly better against Trump than Biden does.

(5,376 posts)Likely voter models are a black art, we all know that about polls.
"unskewing" any one particular poll just seems like cherry picking results.
As I always say...
The polls are what the polls are.
But, we can all relax, real voting starts within a handful of weeks.
Then we will have real data to discuss.

(5,111 posts)Typically youd want the same sample size for both subgroups so that you can break it out by demographic breakouts, subgroups, etc. however when they report the totals they apply a weighted average to bring it back into line. Hope that makes sense. BTW I do this for a living.

(49,004 posts)should make a note of that and link to the other poll.
Right now, if someone just refers to the Reuters/Ipsos GE poll done Dec. 18-19. there's no way to know which one they're referring to.
That's particularly important to anyone concerned about Warren's polling versus Trump, since in one poll she loses to Trump by 2 points, and in the other she beats Trump by 2 points.
And since the poll where she loses to Trump by 2 points is the one where they apparently overpolled Repubcans, I don't think they fixed the problem with reweighting. That poll with too many Republicans also had Biden and Sanders doing a couple points worse against Trump.
