The free-market conservative group’s ad focuses on the border adjustment tax, or BAT, being tossed around by House Republicans.
The plan would levy a 20 percent tax on imports while giving tax breaks to companies that export goods, which opponents say would quickly raise prices on many goods Americans depend on.
The BAT is being considered as part of a strategy that would balance the keep government revenue steady if lawmakers stick to their plan of cutting the corporate tax rate from 35 percent to 20 percent.
The ad calls Roby out for votes made while President Barack Obama was in office and says her refusal to oppose the BAT tax could lead to a spike in gas, clothing, food and school supply costs that could cost Alabama families up to $1,700 a year.
“Congresswoman Martha Roby proudly voted for Obama’s wasteful energy spending, but she’s shy about fighting a trillion-dollar tax hike Congress is cooking up,” the ad narrator said.
The ad closes by asking viewers to call Roby’s office and tell her to oppose the BAT.
Club for Growth is spending $500,000 on the campaign which, in addition to Roby, is going after Tennessee Republican Rep. Diane Black, South Carolina Republican Rep. Tom Rice and Texas Republican Rep. John Culberson.
