1) The more democracy we have, the better. As Benjamin Franklin once said, "Democracy is two wolves and a lamb voting on what to have for lunch." This is why our Founding Fathers made this country a republic, not a democracy. They believed that the people should have their say, but also that certain underlying rules should remain in place that should take precedence over the will of a simple majority. Ultimately, that's the only way that the wolves and the lambs can happily co-exist over the long haul.
Unfortunately, we've moved so far away from the plain reading of the Constitution that we could fairly be called a post-constitutional society and that has a lot to do with why our government functions so poorly, why politics has become so contentious, and why our nation is slipping into decline. A nation where the law has more to do with the whims of the people in power than constitutional principles is a nation that will become increasingly embittered and unstable over time.
2) When it comes to politicians, morals don't matter. It's no coincidence that most Americans are perpetually disappointed in the honesty of our politicians when they simultaneously believe that the moral failings of politicians have little bearing on their fitness for office. If we put adulterers, degenerates, and crooks in office, they're going to lie to us. Why would anyone expect anything else?
What's worse is that they're changing the culture inside and out of Washington. After Bill Clinton, why should anyone be surprised at Anthony Weiner? After Gerry Studds got away with having a sexual relationship with a 17 year old page, why should anyone be surprised that Barney Frank got away with having a gay prostitution ring running out of his apartment? The impact on society is even greater not only because politicians are prominent, but because it's assumed they are held to a higher standard than the average person. If a pothead who liked to snort a little coke, like Barack Obama, can become President, what message does it send to kids about drugs? If Bill Clinton's adultery is treated like no big deal by his wife, Democrats, and the voters, what message does that send to men across the country? We've allowed Washington, D.C. to become a pig pen and no one should be surprised at how dirty all of us are getting in the process.
