Conservative advocacy group Freedom's Watch will broacast radio ads in the 18th Congressional District beginning today through next week attacking U.S. Rep. Zack Space (D-Dover) on his votes on oil and gasoline. Today the group will use automated calls to hit Space on gas prices as well.

The radio ad mentions the rising cost of gas and groceries, then hits Space for having "voted 4 times - against environmentally safe domestic energy production … voted against American energy independence."

It continues, "Producing our own oil would help lower costs and create more American jobs. But Zack Space stands in the way … while we cut back on gas and groceries, family outings, and summer vacations."

Fifteen other House districts are being targeted across the country.
