Beau Biden, the oldest son of Vice President Joe Biden, said today that he is "absolutely" considering a run to fill his father's unexpired term in the U.S. Senate for Delaware.

Biden is currently the attorney general of Delaware and just returned from a tour of duty in Iraq as a member of the Army National Guard.

In an interview this morning on ABC's "Good Morning America," the younger Biden discussed his experiences in Iraq and whether the United States should increase the number of troops in Afghanistan, as happened with the "surge" in Iraq in 2008. "We need to be careful to understand that these are two different wars," he said. "What works in Iraq won't necessarily work in Afghanistan; they are fundamentally different places." Biden listed the two countries' different government structures, geographic sizes and cultures as factors that distinguish them.

"The soldiers are going to do exactly what's asked of them by the commander-in-chief," he said. "The president is doing exactly the right thing in taking the time to make this assessment."

Chris Cuomo then asked Biden is he is planning to run for his father's old seat. Biden said he wants to first reconnect with his family and his job, but added: "Am I considering it? Absolutely, absolutely, but I'll be making that decision in due course."

Vice President Biden hinted at his son's plans at a St. Louis fundraiser Thursday night for Robin Carnahan, a Senate candidate in Missouri whose father had been the state's governor. Biden told the guests, "I find it a hell of lot harder to watch my kid run" than himself. Looking at Jean Carnahan, Robin Carnahan's mother, he said: "I may need a little bit of advice from you."

Joe Biden's seat is currently held by Sen. Ted Kaufman, the vice president's former top aide in the Senate. When he was appointed by the Democratic governor of Delaware to the fill the seat earlier this year, Kaufman committed not to run for a full term in 2010. Sources close to Biden told The Washington Post at the time that Democrats were holding the seat open for Beau, who had deployed to Iraq by the time his father became vice president in January.

Rep. Mike Castle, a popular Republican congressman from Delaware, announced recently that he will run for the seat in next year's special election.
