Political Advertisements: How Far is Too Far?

After our discussion in class about political advertisements, I wanted to see if today's political ads were just as uncalled for and vicious as ads used in previous years.
Considering this was an election year, it was fairly easy to find political advertisements relevant to today's issues. This one however completely shocked me, for it viciously attacks Mitt Romney by implicitly blaming him for a woman's death.
The ad, sponsored by Barack Obama, starts off with a man claiming that  Romney's plans to cut down a power plant directly affected his life. He states that once he lost his job, he could no longer afford health insurance. Because of this, he states that his wife hid the fact that she was seriously ill. It wasn't until the man himself saw that his wife was sick that he brought her to the hospital. Unfortunately, she was diagnosed with stage four cancer and died twenty-two days after her diagnosis. Overall, the ad implicitly states that if Romney had not closed down the power plant, then this man would have been able to provide proper health care during the early stages of his wife's cancer. If this happened, he possibly could have saved her life.
I'm not saying this is a bad ad because it attacks Mitt Romney; I am personally not a fan of his and did not vote for him in this election for various reasons. Yet, I still think this ad crosses the morality line. Yes, it was horrible that Romney closed the power plant down. Still, stating that he caused someone's death, especially when it was done indirectly, gives the ad's audience a false impression of Romney. I know Romney is not a good candidate for President, but he is definitely not a murderer.
This ad specifically relates back to the flower girl ad presented in class Thursday. It attacks our need to nurture and protect. When I first saw this ad, I initially felt sorry for the man for losing his wife. After a second look, I realized that this ad is exaggerated and dramatized. Because of this, many are left stunned and angry at Romney for allowing this to occur. In reality, Romney probably didn't know this resulted until he saw the advertisement. Presidential candidates have much more to do than focus on individual accounts of loss. All in all, this ad pushes the envelope and I believe it could have carried the same message in a less extreme manner.
