No Speaker of the House?

As the House votes member by member on the nomination of Republican John Boehner to Speaker of the House, exactly who holds the position at this very moment?

While Nancy Pelosi will be the one to ceremoniously hand over the gavel after the culmination of the vote, she doesn't actually hold the position now. Pelosi's term as Speaker ended at noon on Monday, which means there actually is not a House Speaker until, as expected, Boehner is sworn in later today.

Behind the vice president and speaker of the House, the Senate president pro tempore is the third in line to the presidency, which means if anything happened to President Obama and Vice President Biden before today's vote, Sen. Daniel Inouye (D-HI) would be president.
