Hillary Clinton famously stated in a Senate oversight committee on the Benghazi debacle " what difference, at this point, does it make?" - The Oculus -

It is the quintessential paraphrase of " what's done is done, let it go" - Jason Jacoby

It is the quintessential unsaid theory of the wrap up of the Biden debacles.

• The stench of the hypocrisy from Democrats and the MSM over crucial failures by Biden himself and his policies is overwhelming.

They have been forced to admit
1. Biden was mentally incompetent pretty much his entire 4 years
2. The border wasn't secure
3. Inflation wasn't transitory
4. Virtually every aspect of the Covid management was a lie
5. Hunter's laptop was real
6. Russia Gate was a hoax
7. Biden committed an offense with his documents scandal but was let off because of his mental infirmity
And more...
Their unbelievable explanation is that they're just discovering it although it was all in plain view and the evidence had been laid out.
Frankly, they've been caught in a lie and they know it...
