Many of us are following the US midterm elections and the most entertaining, shocking and disappointing parts of any election are the TV ads. Here’s where things really get interesting and often very dirty. Take a look at few that are in today’s news:

The good: Michael J. Fox The actor, who suffers from Parkinson’s disease, has done a series of political ads supporting candidates who favor stem cell research. Watch the TV ad he made supporting Missouri Senate candidate Claire McCaskill.

The bad: A political TV ad targeting a black candidate for Senate (Democrat Harold Ford Jr.) contains what critics, including the NAACP, are calling racist sexual innuendo about a black man and white woman. This ad features a series of characters facetiously declaring their support for Ford. Read more about this: AP article.

The ugly: Right-wing radio host Rush Limbaugh is, in my opinion, the ugliest of the uglies. To Rush Limbaugh on Monday, Michael J. Fox looked like a faker in the ad above. “He is exaggerating the effects of the disease,” Limbaugh told listeners. “He’s moving all around and shaking and it’s purely an act. . . . This is really shameless of Michael J. Fox. Either he didn’t take his medication or he’s acting.” You can listen to his comment here.
