The Hill reports:
Hillary Clinton and her tight inner circle have made a decision about who her running mate will be and the campaign is expected to make that announcement Friday, sources say.
One source familiar with the process said Clinton is expected to let her supporters know who she picked sometime Friday, possibly before an afternoon event in Tampa. That announcement may come through a text message or email, the source said. The two candidates will likely campaign together tomorrow in Miami.
So far, much of the Clinton camp has been kept in the dark about the potential pick, with even top advisers guessing about who the pick might be. But those who know Clinton best point to Sen. Tim Kaine (D-Va.) “I would bet all my chips on Kaine,” one confidant of Clinton’s said Thursday.
The two other finalists are believed to be Sen. Cory Booker and Agriculture Sec. Tom Vilsack.
