>If every politician is a liar, then why don't you run for office? If all of the honest people that complain that politicians are dishonest actually got off their butts and started taking over their local governments, then you wouldn't have that problem.
In the off chance you see this (since this post has been flag-killed), I'll answer this question for you.
I worked on the tech team of a well-known political consulting firm for a few years out of college. While I was not a consultant myself, nor have I run for office, I have seen up close what it takes to get elected.
First of all, by far most politicians are egoists to the point of being sociopathic. This is not a coincidence, this is who our current political system favors. It's not necessarily all the fault of our forefathers, however (who definitely had the right idea, just the wrong implementation). It's the particular combination of two-party democracy with mass media that has led to this state of affairs. To get ahead in this environment, it's a huge help if you believe that you are dramatically smarter, better-looking, and more charming than the next guy or gal.
Rational people, who are able to quantitatively and honestly say to themselves, I'm pretty smart, but X and Y are better analytic thinkers, and Z and W have better social intelligence, are at a distinct disadvantage in this kind of system.
And then, there are a handful of true idealists who have succeeded in this environment. Without exception, and regardless of party, all of these people have compromised at least some of their core values, and few of them are able to even accomplish the smallest of tasks to further their ideals, because of all the moral and ethical compromises that they have made to get to where they are.
And then there are a very small handful of idealistic people who hang on to most of their ideals, and manage to gain a respectable number of followers. When they move to make big gains, the system crushes these outliers. I give you Howard Dean and Ron Paul as examples of this phenomenon on opposite ends of the political spectrum.
So no, individual honest people, by their very nature, have very little chance at winning elections in this kind of system. Collectively, they have no chance.
The system is fundamentally broken, and the sooner smart, intelligent people are able to admit this, the sooner we can fix things.
Edit: I will add one thing that you're absolutely correct about. Local (county and municipal) government is the last bastion of honest people (and the only elections I still vote in), because it's the one place where traditional campaigns are not run. Particularly in small counties and cities, people are elected on their actual reputations instead of how they run a campaign.
But when they try to move up to Congress, they have little chance against a well-funded politician of the type I describe above (and absent self-funding by a wealthy candidate, the dishonest politician will inevitably raise more funds, since it's easier to raise funds if you have no moral or ethical boundaries about who you accept funds from, and how you raise them).
