It doesn’t take much for the nation’s voters to become concerned that President Biden, the oldest new chief executive at 78 years old, might not be up for the job.

The latest proof: His resistance to holding a full-blown press conference now 49 days into his presidency has half the country worried.

In the latest Rasmussen Reports survey of likely voters, 50% said they are not confident that “Joe Biden is physically and mentally up to the job of being president of the United States.” Another 48% have confidence in Biden, though only 34% were “very confident” that he was up to the job.

Driving that, Rasmussen said, was Biden’s refusal to meet with reporters. He has had some interactions with the small pool of reporters, but his sometimes awkward speaking style has led to criticism. And the White House has recently cut short his appearances.

Rasmussen said today 52% of likely voters are concerned that he hasn’t held a press conference and that 46% aren’t.

And 76% of those not confident of Biden’s ability are very concerned about the lack of press conferences, Rasmussen added.

The split decision on Biden so far comes as the White House has also been silent on the president giving a State of the Union address. Proponents are shocked he hasn’t made his way to Capitol Hill to declare the opening of the new Biden era and share his plans.

But the results shouldn’t be surprising considering preelection polling that showed many voters were concerned that Biden would resign before the end of his first term.
