The campaign arm of House Democrats is planning to air radio advertisements critical of six Republicans who opposed President Obama’s economic recovery law.

The Democratic Congressional Campaign Committee (DCCC), which is defending the party’s House majority in the 2010 midterm elections, said Thursday that it will run the ads next week in the districts of Michael N. Castle of Delaware; Ken Calvert of California; C.W. Bill Young of Florida; Thaddeus McCotter of Michigan; Charlie Dent of Pennsylvania; and Michael McCaul of Texas.

The ad says that the Republican members, in opposing the stimulus law, “voted against tax breaks” to assist struggling families. No House Republican voted for the stimulus package, which GOP lawmakers generally said spent too much money. Castle said the measure had “too much unrelated, unfocused spending.”
