What does a Vice President do?

WE'VE MOVED! Democratic Convention Watch is now at http://www.DemocraticConventionWatch.com

In general, when someone applies for a job, they know what it is. If someone offers you a job, they will hopefully be able to explain to you what your duties are, if you didn't know already.

I bring this up because last month Sarah Palin said:

"As for that VP talk all the time, I’ll tell you, I still can’t answer that question until somebody answers for me what is it exactly that the VP does every day?"

Some people think the Democrats should be worried about Palin as a pick. But me, I have to wonder: if John McCain still can't count houses, and Sarah Palin doesn't know what she'll do with her days if she wins, how worried should we be?

Then again, maybe Andy Borowitz has it right:

Sen. John McCain (R-Ariz) used the announcement of his vice-presidential pick, Alaska Governor Sarah Palin, to blast the experience of his Democratic rival, Sen. Barack Obama (D-Ill), arguing that Sen. Obama has never been the mayor of a 5,000-person town.

"The Presidency of the United States of America is the toughest job on the planet," Sen. McCain said. "And my friends, the best testing ground for that job is being the mayor of a 5,000-person town in Alaska."

Sen. McCain unleashed a savage attack on Sen. Obama, claiming that his Democratic opponent would be "at a loss" when faced with the challenges of running a 5000-person municipality in Alaska.

"Let's say a constituent calls you and says that a caribou has wandered onto his front lawn," he said. "My friends, Barack Obama wouldn't know what to do."

He used the hypothetical situation to draw a sharp contrast with his vice-presidential choice: "Sarah Palin would take out her gun and shoot the caribou."

Mr. McCain said that an understanding of foreign affairs, Congress, and other issues that a president has to deal with is "overrated," adding, "That's what ‘Presidency for Dummies' is for."

While saying that her "vast experience" was the main reason he selected Gov. Palin, Sen. McCain said that she also had the other three qualifications he was looking for in a vice president: "She is pro-life, pro-drilling, and willing to housesit."
