Meet David Weprin, Democrat seeking to replace disgraced former Congressman Anthony Weiner (another Democrat). He has no freaking clue as to the size of the national debt.

Democrat David Weprin (top photo), an assemblyman and former city councilman, said he is running because it is a “very exciting time fiscally, with the nation’s debt situation, with the debt ceiling, with the deficit.”

He touted “a unique background and something to contribute, having a 20-year private-sector career in public finance as well as being the City Council chairman of the Finance Committee for eight years.”

Soon after, the following exchange took place:

Daily News: “Right now, how big is the debt?”

Weprin: (Pause) “Trillions.”

News: “But how many?”

Weprin: (Deer in headlights look.) “I got caught up on this once before,” referring to his inability while running unsuccessfully for city controller in 2009 to state that office’s budget.

News: “This is central to what is going on in Washington.”

Weprin: “About 4 trillion.”

News: “Four trillion is the debt?”

Weprin: “Right.”

There are lost Amazonian tribesmen who know the national debt has topped $14 trillion. But not David Weprin. He’s stuck some decades back.

No wonder this guy thinks simply ending the wars in Iraq and Afghanistan will solve our fiscal crisis. His perception of the size of the national debt is off by more than $10 trillion.

And as Ace notes, Weprin didn’t get tongue-tied or misspeak. He gave a complete and utter guess. He has no clue. All he knows is “trillions”. And he can’t even manage to come close.

But hey, who needs specific numbers when you’re running for Congress. Just like who needs specific numbers when you’re running for city controller. Just details. Just details.
