Unethical Campaign Ad

Senator Wendy Davis approved a campaign ad that was an attempted stab at her opponent for being in a wheelchair.  She used an empty wheelchair and made remarks about her opponent using sympathy for his handicap.  It is the epitome of unethical politics.  It is almost a concern that a network would approve to play such an ad. As it says in the article, Wendy Davis will not be able to continue climbing the ranks of the Texas government.
