(CNN) – Newly named VP candidate Joe Biden will heavily focus on his personal biography and Senate experience during his speech at the Democratic National Convention on Wednesday night, the first opportunity most Americans will have to hear from the six-term senator.
In his highly anticipated prime-time address, the Delaware Democrat will also hit longtime Senate colleague John McCain hard on a wide range of issues and say the Arizona senator represents four more years of Bush administration policies, a Democratic source involved in crafting Biden's speech tells CNN's Dana Bash.

Specifically, the source says, Biden will discuss his humble upbringing in Scranton, Pennsylvania, and the lessons he learned growing up in a working-class family.
Biden, first elected to the Senate in 1972, will also heavily focus on increasing economic hardships for middle- and working-class families, and say that many of those families are worse off than they were eight years ago.

Biden is also expected to offer a personal perspective on Sen. Barack Obama, whom he first came to know when Obama gained a seat on the Senate Foreign Relations Committee. Biden now serves as chairman of that committee.
Biden, whose foreign policy credentials are widely believed to have landed him on the Democratic presidential ticket, is also expected to outline why he believes McCain and Bush’s foreign policy worldview has ignored the most dangerous threats facing the United States.
