The Bob McDonnell campaign has done the calculations, and it turns out Creigh Deeds' tax policies would cost Virginia families $7,800 over four years and result in the killing of 56,000 jobs, as it states in a new TV ad.

These numbers are based on Deeds' support for a 20-cent gas tax increase and the climate legislation bill passed by the House; although according to the National Association of Manufacturers report that the job loss number is based on, this total would not occur until 2030.

The campaign did not immediately return a message regarding the size and location of the ad buy.
