An influential business group’s latest ad in support of Pennsylvania Sen. Patrick J. Toomey compares the Republican to a Philadelphia staple.  

In the spot from the U.S. Chamber of Commerce, part of the group’s effort to back Republicans like Toomey in tough Senate contests, the senator is compared to putting Cheez Whiz on a cheesesteak, while Democratic challenger Katie McGinty is compared to Silly String as part of a mock focus group .  

The canned cheese product is a key ingredient in an authentic Philly cheesesteak.  

Another segment of the ad compared Toomey to ham on a sandwich, and McGinty to a hamster.  

In response to a query from CQ Roll Call, a Pennsylvania Democratic Party spokesman pulled out a full range of cheese puns.  

“In queso trouble, Pat Toomey always relies on Wall Street cheddar. It whiz a ham-handed attack, but they bleu it,” said Preston Maddock. “Feta luck next time.”

The commercial itself is part of what the Chamber describes as a seven figure ad buy, and it will be running on both cable and broadcast networks in Philadelphia. It comes as part of the group’s broader effort which features an overall eight-figure buy with an emphasis on Senate contests, including those in Ohio, New Hampshire, Wisconsin and Arizona.
