Which cabinet member would make the worst president?

[Yelnoc]

Let's say there is an attack at the State of the Union address and everyone in the presidential line of succession is killed, leaving the designated survivor to lead the nation. Of all the cabinet members, who do you think would make the worst president?

For reference:

State: John Kerry
Treasury: Jack Lew
Defense: Chuck Hagel
AG: Eric Holder
Interior: Sally Jewell
Agriculture: Tom Vilsack
Commerce: Penny Pritzker
Labor: Thomas Perez
HHS: Sylvia Burwell
Education: Arne Duncan
HUD: Julian Castro
Transportation: Anthony Foxx
Energy: Ernest Moniz
VA: Robert McDonald
HS: Jeh Johnson

First off, Sally can't be president since she was born in Britain.

It would be Holder just because he is now the most partisan of the members.

Arne Duncan, probably.

[Chancellor Tanterterg]

Arne Duncan, probably.

[IceSpear]

Arne Duncan, probably.

[Mr. Smith]

Vilsack easily.

[Mister Mets]

Moniz, Perez or Pritzker would be nominees. Their backgrounds don't seem to be the best fit for potential Presidents.

Kerry and Hagel have been Senators.
Foxx and Castro were big-city mayors.
Vilsack was Governor.
Jack Lew was OMB Director and White House Chief of Staff.
Sylvia Burrell was OMB Director and Deputy Chief of Staff.

Arne Duncan has been Education Secretary for some time, and run a tough bureaucracy as superintendent of Chicago schools.

Holder might have a tough time shifting from relatively free rein as AG to the presidency, but he would have had many years in the national spotlight.

Johnson has eclectic experience as assistant US Attorney, and General Counsel to the Air Force and Department of Defense.

McDonald was CEO of one of the largest and most successful companies on the planet (Procter & Gamble.)

Pritzker

[Atlas Has Shrugged]

Castro by far is the most dangerous of the bunch, but they all (besides Kerry, the incoming AG Lynch, Burrell, and Foxx) are terrible.

[Grumpier Than Uncle Joe]

Holder

[New_Conservative]

Holder

[publicunofficial]

Holder or Duncan probably.

[Illuminati Blood Drinker]

Arne Duncan, probably.

[TNF]

Tossup between union busters Pritzker and Duncan.

[TDAS04]

Arne Duncan, probably.

[Bigby]

Tie between Duncan and Holder.
