We are familiar with paintings depicting the solemn majesty of the Declaration of Independence. However the reality was that the individuals concerned argued passionality - there was real conflict. John Hibbing and Elizabeth Theiss-Morse explain why the US Congress is held in low opinion by many people. (The same applies to the UK Parliament) - [from "What is Wrong with the American Political System" in 'Congress as Public Enemy'.]
"If open debate is seen as bickering and haggling; if bargaining and compromise are seen as selling out on principle...it is easy to see why the public is upset with the workings of the political system." But "What seems to escape many people is that democratic processes are practically by definition not procedurally efficient. The 'haggling and bickering' so frequently decried by the people could be very easily termed informed discussion..."
The Muppets portrayed the events of the Continental Congress in a sketch performed a few years ago. The truth they highlight is that democratic politics has ALWAYS been messy.
