Trump didn't pay for this one...
CNN Poll: Biden faces negative job ratings and concerns about his age as he gears up for 2024
#24 | POSTED BY WHATSLEFT

No, but some are questioning the legitimacy of that poll:

CNN desperately wanted an anti Biden narrative so what did they do? They commissioned a poll comprised of 59.7% Republicans(!) to generate a predictably bad outcome for Biden and have now blabbed about it nonstop all day.

. . .

It's even worse. Based on the excerpt you provided, it's 59% Republicans/Republican leaning and 26% Democratic/Democratic leaning. (The other 15% truly independent or who knows since 20% we're not registered voters). This means there were more than TWICE as many Republicans polled as Democrats. Reminds me of that saying; there are lies, damn lies, and statistics. Perhaps needs to be updated to lies, damn lies, and CNN polls?

#26 I know you don't understand statistics Gal, but wouldn't that lopsided percentage show more pronounced in the polls?
Why do I say that?
Well here is how the poll was actually conducted....
Results among the full sample have a margin of sampling error of plus or minus 3.5 points; among registered voters, the margin of sampling error is 3.6 points, and it is 6.0 for Democratic and Democratic-leaning voters.

CNN wants Trump to run, and Biden to win.

I understand the parameters of this poll well enough based on the info provided. Margin of error tells the story:

"Results among the full sample have a margin of sampling error of plus or minus 3.5 points; among registered voters, the margin of sampling error is 3.6 points, and it is 6.0 for Democratic and Democratic-leaning voters."

I would find the poll more convincing in the margin of error was around plus or minus 3.5 across the board.

"Why would CNN desperately want an anti-Biden narrative?"

Because they want a horse race. They want viewers and clicks.
