Democratic presidential nominee Barack Obama and Republican nominee John McCain meet tonight at Hofstra University in New York, their final scheduled appearance together before election day.

The third encounter was meant to be the debate to focus the economy and domestic issues. But the economy couldn’t wait.

The $700 billion government bailout was the first topic at the almost-didn’t-happen-first-debate with PBS moderator Jim Lehrer.

Tom Brokaw of NBC News selected his first question from Allen Shaffer, who asked about on the economic downturn and retirees at the Town Hall meeting.

CBS anchor Bob Schieffer moderates tonight’s debate, hours after the Dow Jones Industrial Average and the benchmark S&P 500 suffered their worst one-day percentage drops since the 1987 stock market crash .

And Federal Reserve Board Chairman Ben Bernanke told a group of economists in New York that policymakers may need to use their regulatory authorities to predict and curtail asset bubbles in the future so that we don’t see such wild swings in the economy.

What would you ask if you were in Schieffer’s seat?
