Political ads gone too far

Have you been watching t.v. lately?  Have you seen the multiple ads attacking different candidates?  I'm sure you have.  There are so many!  If you haven't seen one just turn on the t.v.  There you go.  You'll see one after the other.  It's crazy and most of the ads aren't positive.  Probably about 98% are negative.  That's pretty sad.  I even hear them on the radio!  I think that the ads have gone way too far and I think that they do nothing to change the voters opinions.  They are just annoying.  I think that the ads shouldn't be a allowed unless they are positive.
