With a runoff in the House of Representatives?

That's what it'll come to, y'know. We're still saddled (pun intended; see Jody's thread) with the Electoral College.

Hmmm... The 12th Amendment says:

The person having the greatest number of votes for President, shall be the President, if such number be a majority of the whole number of Electors appointed; and if no person have such majority, then from the persons having the highest numbers not exceeding three on the list of those voted for as President, the House of Representatives shall choose immediately, by ballot, the President.

[emphasis added]

And the 20th Amendment says:

Section 1.

The terms of the President and the Vice President shall end at noon on the 20th day of January, and the terms of Senators and Representatives at noon on the 3d day of January, of the years in which such terms would have ended if this article had not been ratified; and the terms of their successors shall then begin.

And one of the unamended portions of Article II itself (just below the part amended by #12) says :

The Congress may determine the Time of chusing [sic] the Electors, and the Day on which they shall give their Votes; which Day shall be the same throughout the United States.

[source: The National Archives, of course!]

I can't find a requirement for which House decides -- that is, the incumbent before January 3, or the newly sworn-in. [Wikipedia's article on the Electoral College, q.v.] But let's say, just for s&g's, that it will fall to the new House. That may throw those elections into an entirely new kind of cocked hat (with a feather named "Macaroni"?), as well... Every voter of each district will be conscious of the impending possibility, and races may be decided on one issue: which Presidential candidate the House candidate pledges to vote for.

As I recalled before, less than seven months remains until Feb 8., when I am certain the major party candidates will be chosen for anointment at their respective conventions. But 16 months remain before Election Day 2008, and another two until the new Congress is sworn in. Could get interesting...
