I still don't know why the GOP didn't use this $2,500 lie during the HCR debate

They should have been beating the (so-called) moderate Dems over the head with this for the past few months.

Obama’s broken promise couldn’t be any clearer. Force he and the Dems to try to tap dance with “they’d be $2,500 higher otherwise” but the average person on the street would see right through that.

Instead, the Republicans barely ever mentioned it. Why??
