Dancing With the Stars pro Mark Ballas is a class act.

Our photogs questioned Ballas last night about why Bristol Palin hasn't gotten kicked off the show and he replied with: "Because she's relatable... she's the most normal person we've had on the show."

And even though I don't think that's the only reason, Ballas remained polite and explained further, adding "There are over 20 million viewers of the show. I guarantee you all of them are not Republican." True that! Watch our vid of him and Chelsie Hightower above.
