The other thing that I like about Biden is his blue collar roots and being someone who is representative of the every man. He knows what it's like to have to scrimp unlike 7 houses McCain (Biden's net worth is between 100,000-150,000). If McCain picks Romney for his V.P. which seems likely then that'll be the Richy Rich ticket. Joe Biden could have cashed in but like Obama he gave up a lucrative law career to be a public servant, a fighter for the people.
Biden is a family man. He goes home every night back to Delaware from Washington D.C. to be with his family, riding the train like any other person commuting to and from work.
He has been a strong fighter and champion for women's rights:
Joe Biden led the fight to criminalize violence against women and to hold batterers truly accountable by writing the ground-breaking Violence Against Women Act (VAWA) in the 1990s.And he brings some major foreign policy credentials to the Obama campaign being the current Senate Foreign Relations Committee Chairperson.
However, there remains work to be done, so in 2007, the Senator introduced the National Domestic Violence Volunteer Attorney Network Act, an innovative initiative that would recruit volunteer lawyers and match them with domestic violence victims.
So all in all, Biden was a good choice--he's the full package.
