Why else do you imagine she was in Iowa yesterday? Because Tom Harkin's cooks grill up a mean prime rib? Please. Nope, she lost Iowa to Barky back in aught-eight, and she's out there trying to give them another chance "to get to know her".
She wouldn't be doing that if she wasn't campaigning. The only question is who she's going to tap as Veep. But what difference, at this point, does it make?
This isn't about the coming November elections. It's about the ones two years from now.
