What would happen if the President Elect and Vice President elect died before taking office?

Yes, it is called the chain of command or line of succession it is:

1 Vice President of the United States Joe Biden (D)

2 Speaker of the House John Boehner (R)

3 President pro tempore of the Senate Daniel Inouye (D)

4 Secretary of State Hillary Rodham Clinton (D)

5 Secretary of the Treasury Timothy Geithner (I)[3]

6 Secretary of Defense Leon Panetta (D)

7 Attorney General Eric Holder (D)

8 Secretary of the Interior Ken Salazar (D)

9 Secretary of Agriculture Tom Vilsack (D)

10 Acting Secretary of Commerce Rebecca Blank (D)

11 Secretary of Labor Hilda Solis (D)

12 Secretary of Health and Human Services Kathleen Sebelius (D)

13 Secretary of Housing and Urban Development Shaun Donovan (D)

14 Secretary of Transportation Ray LaHood (R)

15 Secretary of Energy Steven Chu (D)

16 Secretary of Education Arne Duncan (D)

17 Secretary of Veterans Affairs Eric Shinseki*

18 Secretary of Homeland Security Janet Napolitano (D)

The chain would go to the person holding the highest position that was actually in office, so it would go to John Boehener.

Amendment 20 - Presidential, Congressional terms. Ratified 1/23/1933 three. If, on the time constant for the establishing of the term of the President, the President pick shall have died, the vice president pick shall become President... Until, J. Biden can not be certified for the place of business of the presidency then the legislation is apparent and not subject to " misinterpretation". Joe Biden would emerge as the next president of the USA a 12:00 on Jan. 20, 2009 absent a gross uprising in the electoral college.

Dick Cheney automatically will assume office and disband Congress and the Supreme Court and declare himself "Dictator in Chief" and will then funnel massive amounts of money into medical technology to keep himself alive indefinitely.

If I remember rightly, the President of the Senate is the next in line of succession.

No, the Speaker of the House would then be President.

Since Obama and Biden are in right now...We'd all laugh.
