Slam campaign, scare ads, and discrediting the opponent are campaign techniques. Effictive ones at that. To say Republicans don't use this technique would make them martyrs for their cause. And it makes you naive.
I live in the Chicago area, this past election was nothing but slam campaign on both sides.
An interesting observation is that you discredit opinions so flipantly. Anything stated by someone who is not right next to you on your skewed political views has no say or is always incorrect. You have an opinion, I have an opinion, we all do. It's our right to voice that opinion. It is also your right not to listen to others opinions. It makes you narrow minded, but it's your right.
