The longtime and often fierce loyalist of the New York senator launched a petition Wednesday night in hopes of landing Clinton on Barack Obama's presidential ticket. The petition, located at womenforfairpolitics.com, directly tells Obama that "Your selection of a vice presidential candidate may make the difference between victory and defeat."
"We write to urge you to select Sen. Hillary Rodham Clinton to be your choice for vice president because we believe that she would be, by far, the most qualified and strongest candidate to be your running mate.
Davis, who has known the Clintons since their law school days at Yale, says he is not acting on the campaign's behalf in launching the petition drive.
"Both you and Sen. Clinton during this campaign have demonstrated strengths in different segments of the electorate and in different parts of the country. Together, you stand the best chance of making U.S. history not once but twice - the first African American president and the first female vice president since the founding of our great nation," the petition also said.
Often appearing on CNN, Davis has been a tenacious advocate for Clinton during the course of the primary season. Following Obama's speech on his relationship with the Rev. Jeremiah Wright in March, Davis expressed concern on the Huffingtonpost.com that Obama still had not answered several questions about the controversial pastor. In a Wall Street Journal Op-Ed a month later, Davis again pressed the Illinois senator to address "unanswered questions" about his former pastor more fully. He also wrote an article on the Huffingtonpost.com in April titled "The Top Ten List of Undisputed Facts Showing Barack Obama's Weaknesses in the General Election Against John McCain."
Davis' petition follows that of voteboth.com, an organization set up several weeks ago by former Clinton aides with the initial mission of landing both candidates on the same ticket, not matter what the order. In recent weeks the group has pivoted to expressly advocating for Clinton to serve in the No. 2 spot.
That petition includes the names of several prominent Democrats, most of whom are supporters of Hillary Clinton's White House bid, including Govs. Ed Rendell and Tom Vilsack and Sens. Chuck Schumer and Dianne Feinstein.
