Full name: Timothy Michael Kaine
Current job: United States Senator from Virginia. Serves on Foreign Relations, Armed Services, Budget and Aging Committees. Term expires January 2019.
Reputation, in one sentence: Personable and pragmatic former governor with an extensive resume in a purple state.
Strengths: Experience as governor? Check. Foreign-policy knowledge as a senator? Yup. Represents an important battleground state? Yes. Tested in high-profile campaigns? Affirmative. A team player (former DNC chair, willing Senate candidate in '12)? You betcha. Speaks fluent Spanish? Yeah, that, too.
Weaknesses: He's more of an establishment politician than a Bernie Sanders/Elizabeth Warren-style progressive, so Sanders backers might not do cartwheels over a Kaine pick. There's also that "wandering eyebrow" from Kaine's State of the Union response in 2006.
Born: February 26, 1958 in St. Paul, Minnesota. Raised in Kansas City, Missouri.
Family: Wife - Anne Holton. Children: Nat, Woody, and Annella.
Previous gigs: Richmond mayor, 1998-2001. Virginia Lt. Gov, 2002-2006. Virginia Gov. 2006-2010. Democratic National Committee chairman, 2009-2011.
Good to know: Kaine's office notes that fewer than two dozen people in U.S. history have served as a mayor, a senator and a governor.
Fun fact: Kaine plays the harmonica, although he admits he's not great at it. Hetold the Washington Post in 2015: "I've had people comment less than favorably on my quality."
