When there is political disagreement and deal-making is it true that politicians are not acting according to the common sense consensus of the people?Question deals with Political science
On the contrary, when there is disagreement and deal-making, politicians are acting according to the "common sense consensus" of the people much more than when they try to push extreme ideas through Congress.
People in the United States are still generally more moderate than they are extreme. It is true that the consensus of people who vote in the primaries tends to be more extreme, which is why we see a moderate like Mitt Romney having so much trouble winning the Republican primaries this year. However, most of the country as a whole is not that partisan and tends to want the parties to stop trying to push extreme positions.
We can see this, for example, in this link where we can see that the majority of people in the country want the deficit to be cut through both spending cuts and tax increases. This is a moderate position that demands compromise and deal-making and it is also one that reflects the "common sense consensus of the people."
