The Draft Biden super PAC has launched an ad campaign trying to encourage Vice President Biden to enter the 2016 Democratic presidential nomination contest, using his personal story of trying to overcome tragedies with his family to find "redemption."

It marks an intensifying effort to demonstrate that there is enough financial support among Democratic donors to support a late-breaking entry by Biden, who has spent the past two months considering the presidential race following a mourning period after his 46-year-old son, Beau, died May 30 after a long battle with brain cancer.

The 90-second spot does not mention his son's death, only alludes to it, but it traces the arc of Biden's 43-year career in Washington, beginning with the December 1972 car crash that left his first wife and daughter dead and his two sons in a hospital trying to rehabilitate.

"By focusing on my sons, I found my redemption," the vice president says in the ad, using his own words to tell the story.

It comes from the "Yale Day" speech Biden delivered the day before the Ivy League school's commencement, as he knew his son's fight with cancer was unlikely to succeed. Beau Biden died two weeks after that speech.

An adviser to the Draft Biden PAC said it was a "six-figure" purchase of ads that would run on national cable TV later this week. NBC's "Today Show" debuted portions of the ad Wednesday morning.

The ad was produced by Mark Putnam, a Democratic consultant whose specialty are personalized videos that have been praised by Democratic and Republican consultants.

Biden has put off making a decision beyond several purported deadlines from his small group of advisers, leading to the decision that he is certain to skip next week's first Democratic debate featuring the two front-runners, Hillary Rodham Clinton and Sen. Bernie Sanders (I-Vt.), and several lower-profile candidates.

In his recent public comments, Biden has said that his family's grief from his son's death still consumed them some days and that he was not yet able to make such a big decision. But in recent days, there has been a heightened tension among some Democrats, who feel that the signals he has sent have been more positive toward taking on the race.

An announcement is likely sometime in the last two weeks of October, according to several Democrats who have spoken to the vice president and his closest advisers.

At the moment Draft Biden -- which by law the vice president's advisers cannot coordinate their efforts with -- is the only political entity devoted to Biden. Started practically from scratch a little more than two months ago, the group recently issued a list of 50 Democratic donors willing to finance a Biden presidential campaign.

The group was originally started in Chicago by a few Democrats that were just fans of the Vice President and now relies heavily on Josh Alcorn, the former top political adviser to Beau Biden. Its finance team includes prominent bundlers for President Obama, such as Yolanda "Cookie" Parker, a Los Angeles technology executive who raised more than $2 million for Obama's two campaigns.

The new ad ends with Biden's admonition to Yale's students that serves as the super PAC's own message to Biden: "It will be up to you in this changing world to translate those unprecedented capabilities into a greater measure of happiness and meaning —  not just for yourself, but for the world around you."

Then, on screen, it ends with a two-word note: "Joe, Run."
