In case you haven't heard, McCain has suspended his campaign temporarily in order to go to Washington and work on the bailout plan. Obama has also gone to Washington to meet jointly with McCain and President Bush to discuss possible scenarios.
The difference between the two is that McCain has said the mortgage bailout plan of Freddie Mac and Fannie Mae is more important right now, as the Senate is discussing and attempting to vote on it today. Obama replies by saying "It is going to be part of the president's job to deal with more than one thing at once. It's more important than ever to present ourselves to the American people."
That's perfectly understandable. The POTUS is Chief of State and Commander-in-Chief among many other job titles. However, BARACK OBAMA IS NOT THE PRESIDENT.
As this bailout plan affects the lives of every American, either directly through a bought-up mortgage, or indirectly through the taxes of everyone who has to pay for it, that should be the number one concern of someone who is still employed (as in receiving paychecks) by the people as a Senator. It shows a very large lack of judgment to say the Presidential debates outweigh one's duties as a Senator.
Imagine if I was employed by Microsoft, who is considered a very large company. But instead of working on the problems that Windows Vista seems to create for people who use it, I am instead working on Google's Project 10^100th in the hopes they like my ideas so much they offer me a job with their larger corporation. That would be irresponsible not only to those that employ me at Microsoft, but to those that buy the goods and services I produce.
The thing with Barack is, the people he was elected to serve and the ones who employ him ARE THE SAME PEOPLE! So he has decided to say that future is more important than the present.
