Both Biden and his wife Jill have spoken publicly about what it means to have a loved one overseas and both have said they share a connection with other military families across the nation.
"I look across the room and though I have only met a few of you, I feel as though we are family," Jill Biden said at a recent awards ceremony honoring the employers of National Guard and reservists. "We share the same concerns, the anxieties, the sense of duty, and the pride that comes along with being a military family."
As Beau Biden returns from his year-long deployment, he will return to his previous job as attorney general.
The acting attorney general, Richard Gebelien, who stood in for Biden while he was in Iraq, recently announced that he would step down at the end of this month.
Beau Biden's office could not confirm when he would return to his role as attorney general. He is still on active duty with the National Guard.
Now that he is back in Delaware, cue the speculation about what's in store for Beau Biden's political future.
Delaware will hold an election next year to fill the remaining four years of Joe Biden's Senate term, his seventh, which he won while on the Obama ticket last November.
Biden was sworn into his Senate seat but stepped down before taking another oath of office, as vice president. Then-Gov. Ruth Ann Minner appointed former Biden aide Ted Kaufman to the job, which most took as a sign that the Bidens wanted to keep the seat warm until Beau could step in.
All eyes in Delaware will be on Republican Rep. Michael Castle, a former governor and nine-term congressman, who could make a run for the Biden seat and set up a showdown with Beau Biden.
If Castle does throw his hat into the ring, political observers believe he would be the favorite over Biden, and polls from earlier this year show the Republican with a solid lead. But it is too soon to discount what impact the backing of the White House could have on a potential Biden candidacy and fundraising operation.
One Republican official in Washington called the Delaware Senate picture "unclear at the moment" and said much will hinge on whether Castle decides to run. Castle so far has been mum on any future plans.
Another option for Biden would be to skip next year's Senate election, run for re-election as attorney general and wait for a seat to open up down the road.
The vice president has said Beau would "make a great senator."
He also said he offered his son some political advice this summer:
"Whatever you decide to do, make sure there is something you are willing to lose over," Biden recounted saying in an interview with NBC. "Don't just do it ... because it's the next step. If you conclude that you care deeply about something, and you're willing to lose over it in a campaign, then do it."
