The ads will not be "Look what the Democrats Did for you" - that would be suicide. The ads will be focused on what the "Republicans will take away" - the throw grandma down the stairs type ads all over again.
Ads like.....
40 million (theres that bogus number again) will lose there health care.
Young adults living at home will no longer be covered under their parents plan and must fend for themselves.
Seniors will lose their prescrition drug benifits (that was passed by Bush and not Obamacare - but the people won't remember and it won't be impacted by a repeal of Obamacare).
People with pre-exisitng conditions will lose their coverage and no longer be able to get heathcare.
Tens of Thousands will die for lack of coverage.
I could go on and on. Writting a democrat ad is easy. Just make it sound scary.
