This Sunday...

Romney looks to gain traction and some message control with his swing state bus tour and the rollout of his Vice Presidential pick. One of those contenders, Senator John Thune will join us live from his home state of South Dakota.

It’s the dog days of august, but you wouldn’t know it if you live in a swing state and own a t-v. The campaigns, parties and outside advocacy groups have pummeled voters to the tune 10,483 ads so far this month. Can it get any nastier? We’ll ask Senior Advisers to both campaigns – David Axelrod and Ed Gillespie.

And with Romney-watch in full gear, we look at what his v-p pick says about the state of the campaign with our political panel.

Watch Sunday at 9 a.m. & NOON ET.
