Bill Clinton stuck to his policy principles, by infusing the economy with capital gains tax cuts and cutting welfare. Romney is simply trying to have it both ways criticize Obama for health care reform mandate and running on it the same time. He also flipped flopped on abortion as well, said won't ban abortion in MA. That's why he's gonna have a hard time winning.
Obama has flipped on the following: Immigration, Gitmo, and even flipped on the wars and even the Bush Tax Cuts a little bit. So its a flip against a flop!
