Actually, it doesn't at all. And that's the point. We have a very marginal primary impact on the nation's political debate here, but we have a very large impact on each other. And that's pretty valuable. The discussion that takes place here has the ability to increase our knowledge of events, help us consider an issue from many perspectives, and hash out the many disagreements on policy and strategy that are a trademark of our fractious party. :D But there's a problem.
Disingenuous marketing of ideas kills discussion. Those who have a more direct impact on the national debate use these rhetorical bludgeons all the time (all right wing radio hosts use them!), because their purpose is not always to educate or seek the truth, but rather to promote some ideas while crushing others. The use of these tactics by such people has an impact on debate (witness the BetrayUs ad, the "phony soldiers" comment, etc.), while our use of the same merely has an impact on our fellow DUers, most of the time.
We see it most clearly in the primary wars. Somehow it became a sin to acknowledge any flaw or blemish concerning one's candidate. People will tie themselves in the most ridiculous knots here to try and justify unappealing behavior from a candidate they support. At the same time, people will parrot the most hate-filled vitriol from the worst sources, so long as it attacks a candidate they dislike or view as competition. I'll use Hillary as an example, just because as the frontrunner she generates both extremes. You see both sides of disingenuous marketing, pro and con:
Con "Hillary's IWR vote and belligerence toward Iran make her no different from the Republicans."
Pro "Hillary is forced to do those things because she has to be seen as tough on terror."
Odds are you are reading one or the other and saying to yourself "that is fucking ridiculous" depending on whether you support Hillary or not. Are you at all convinced by the statement you disagree with? Does the statement you don't mind as much show the whole truth? The answer will be "no" in either case, simply because neither statement is very honest or believable. One will bother you less than the other if you're predisposed to agree with its basic rhetorical thrust--Hillary is bad, or Hillary is good.
These arguments fail to promote, in my view, what DU is best used for. They don't educate, as they baldly ignore some facts and purposely inflate others. They don't promote discussion, because such extreme statements aren't made with the idea of getting to the truth or convincing others so much as winning a petty personality war. It destroys the middle ground and turns what could be an honest examination of pros and cons into a social game. Whose wholly artificial and extreme caricature of the candidate will prevail? Sober discussion of platform and history turns into a ruthless search for material to shore up the candidate as either utter villain or snow-pure saint.
For those opposed, positive news is always suspect and negative news is always Gospel. For supporters, it's the opposite. What this causes is the effective destruction of reality, which often lies between the two poles. It discourages productive debate between supporters and critics. Any who see both sides of the issue are stereotyped as clandestine members of one side or the other. Their intent is assumed to follow the same extreme lines of thought as the true partisans. Moderation is seen as a clever disguise for a more radical purpose. A single even-handed post may be seen as a devious attempt to promote a candidate by one side, -and- at the same time as a diabolically subtle attempt to attack the candidate by the other.
It doesn't help anyone, and it's not limited to candidates. I learn the most when people give up the talking points, the marketing, and purposed dishonesty. I get the most out of DU when people are honest in their disagreement. -Admit- that a certain stance of your candidate might be ill-advised or problematic. -Allow- that a candidate you dislike has some good qualities when they are shown.
The best experience I have on DU is when someone completely disagrees with me, presents an honest case, and changes my mind. This rarely happens when someone insults me with dishonesty or stereotypes me into an extreme point of view I never expressed. It's frustrating when someone does it to you, so don't do it to anyone else. We're all guilty of this, but we can also all get better.
