Larry Sabato: Kaine potentially locks up Virginia.

Clinton has been the favorite to win in Virginia since the Republicans chose Donald Trump, whose backing in heavily populated suburbs such as Northern Virginia should lag behind the previous three Republican presidential candidates. But with Kaine on the ticket, Virginia can probably retire its swing-state jersey for this year. A good-size Democratic victory in this once-reliable GOP state should be expected, likely larger than President Obama’s 3.9 point margin in 2012. Recent studies have suggested that a solid running mate can add two to three percentage points in his or her home state.
