During his "My Take," Thursday, "Varney & Co." host Stuart Varney addressed Biden's recent absence from the public spotlight, arguing Democrats are trying to pump up Kamala Harris' visibility and credibility because the president's aging process is "speeding up."

: What is going on? 

The president rarely appears in public and rarely holds a news conference.

But Vice President Harris boosts her public profile and appears before a very friendly media. 

Suddenly she's addressing all the issues. Silent Biden. Talkative Harris.

Could this be a signal from the Democrats that they know their guy will not be president for another 5 years, so they are trying to pump up the visibility and credibility of his vice president?

They've got a tough job.

Appearing on "The View," Harris made a mess of it.

She blamed the Republicans for the border crisis. That's nonsense and hurts her credibility.

She said she was "scared as heck" about a Trump presidency. That's fearmongering.

She said Republicans pick on Biden's age because "they have nothing else to run on."

That's a stretch. Trump is running on his successes in his first term. 

The border, the economy, energy independence, etc.

Finally, she framed the election as a split screen. 

On one side, "competence," that's Biden. On the other "chaos," that's Trump. 

I would suggest that at least some of the chaos was caused by the media, overcome with Trump hatred. 

I'm still looking for any competence shown by Biden.

Today, the president will make his first public appearance of the week. 

He's talking up Bidenomics in Raleigh, North Carolina. 

If he answers any questions, it will be tightly controlled, and his aides will be especially careful about getting him on and off the stage. 

They know the aging process is speeding up. You can see his deterioration.

That's why they are desperate to boost Harris' credibility. It's not going well.
