State Sen. Mick Mulvaney (R) is up with his second television ad of his campaign against House Budget Chairman John Spratt (D).

Republicans have been working hard this cycle to paint Spratt, an old-line Southern Democrat, as a man who has been changed by his 14 terms in Washington.

Titled “There Was a Time,” the ad shows Mulvaney talking in a town hall setting. The key line comes after Mulvaney ticks off a list of his conservative principles, including limiting government and reining in spending.

“There was a time when our Congressman used to believe those things as well,” Mulvaney says. “But those times have changed, and I think it’s time for us to change Congressmen.”

Mulvaney’s first television ad, which went up last week, was a biographical introduction that also hit on his theme of limited government. Mulvaney didn’t mention President Barack Obama in either ad, but both make reference to keeping health care free of government management.

Spratt’s ad campaign began recently with a spot focused on how his years in Congress have translated into good constituent service for the district.
