I hadn't seen much of the male half of Billary in the news lately and there's seems to be a "strategy" behind that. According to Hillary's Secret Weapon For Rural America he's pimping her out on the back roads of rural America.

Mr. Clinton is effective in such settings because rural Americans relate to the former president, said Steve Jarding, a Democratic political consultant who has focused on rural areas.

"It's the 'boy from hope' stuff, the fact that he grew up in a small town," Jarding said. "Someone like John Kerry, and I mean this with respect, looked to people in rural America like a blueblood. With Clinton, I really do get a sense that they believe he feels their pain."

I guess she gets to have her cake and eat it too. With Bill in the background it's less likely (in theory) that he'll open mouth and insert foot. It's also quite possible that this angle is indeed playing to his strengths. Personally I think it's more the former.
