READ: Most voters say Biden's "too old" to run in 2024, another poll finds
- The WSJ poll is the latest to show a majority of surveyed voters' concerns that the 80-year-old Biden might be too old to effectively serve for four more years.
By the numbers: The poll contacted 1,500 registered voters Aug. 24-30 and 750 of these responded to the poll that has a margin of error of 3.6%, per the WSJ.
- Some 48% of voters said Biden was likable, but 60% said he's not "mentally up for the job of president."
- That compares with 31% who found Trump likable and 49% who consider the former president is not "mentally up for the job of president."
What they're saying: Biden addressed concerns about his age during a Labor Day speech in Pennsylvania on Monday.
- "The only thing that comes with age is a little wisdom," he said. "I've been doing this longer than anybody, and guess what, I'm going to continue to do it with your help."
- Representatives for the White House did not immediately respond to Axios' request for comment.
