Millions just witnessed the end of a presidency live on television.

Joe Biden’s performance during the debate was embarrassing.

Whenever CNN put him up on the split screen, he had a thousand-yard stare.

He didn’t look old.

He looked ancient.

He looked empty.

But at least he wasn’t speaking.

Because when it was his time to answer, Biden was incoherent.

He said he “beat Medicaid.”

Asked about abortion, he randomly started talking about migrant crime.

“I really don’t know what he said at the end of that sentence,” fomer President Trump noted at one point, “and I don’t think he knows what he said either.”

At one point Biden just froze.

The administration can’t say it’s a “cheap fake” — everyone saw it happen.

The sound you heard last night was Democratic operatives everywhere screaming at their televisions.

Biden can’t survive this.

It is political malpractice to let him continue to run for re-election.

It is national malpractice to let him continue.

Biden spent an entire week preparing for this debate, and this is the best he could do.

That should terrify everyone.

Let’s say that, shockingly, Democrats don’t intervene to replace President Biden as their candidate.

Say, implausibly, 81-year-old Biden wins.

He won’t be getting any sharper.

During a second term, our president would continue to deteriorate, incapable of making proper decisions.

That would be a disaster for the United States.

On policy, Biden had no answer to the inflation or the border disaster, two of the most important issues to voters.

But sadly that’s almost beside the point.

Biden was so mumbling, so doddering, so lacking in command of the facts, that it overshadowed everything.

Asked about his age, Biden didn’t defend his acuity, instead started reminiscing about the old days, we think in the 1800s.

No wonder the White House keeps him hidden away, keeping him away from the press and public events.

The Democratic elite is pulling a con job on the American people, and it was exposed last night.
