Hillary Clinton will already make history with her nomination for president, becoming the first woman to lead a major presidential ticket. Now the question is whether she wants to do it again with her choice of running mate.
Clinton is expected to name her vice presidential pick sometime after the Republican National Convention ends and before her own convention begins in Philadelphia on July 25.
On her list are several Hispanic lawmakers, African-Americans and at least one woman.
Latino politicians like Housing and Urban Development Secretary Julian Castro offer an appealing contrast to Donald Trump's controversial comments on Mexican immigrants, plus he would bring youth to her ticket.
She also has a close relationship with Labor Secretary Tom Perez, who is beloved by labor unions.
Ohio Sen. Sherrod Brown and Massachusetts Sen. Elizabeth Warren would excite supporters of Vermont Sen. Bernie Sanders. Brown has been a vocal opponent of free trade agreements and is one of the Senate's most liberal members, while Warren was the original progressive hero who has long railed against Wall Street.
But both Brown and Warren, along with New Jersey Sen. Cory Booker, have a big complicating factor — they come from states with Republican governors who would nominate their replacements if the Clinton ticket wins. And with control of the Senate hanging in the balance this November too, losing a Senate seat may be too risky of a gamble for Democrats.
Ultimately though, Clinton may go with a safer, non-historic pick. Virginia Sen. Tim Kaine is a solid choice who was a finalist in President Obama's search eight years ago. Kaine himself has admitted he is a "boring" choice, but boring isn't necessarily a bad thing in politics, and he does come from a swing state too.
That's the same with Agriculture Secretary Tom Vilsack, who has emerged as a late, top possible pick for Clinton. The former Iowa governor comes from an important state and is a longtime friend of the Clintons too.
