One of the wildest things in politics is how neither side of mainstream politics actually does what their rhetoric is. Mainstream democrat politicians and their voters have a lot to say when it comes to criticizing the military industrial complex, yet not one democrat politician hasn't been a war hawk.
On the other hand, republicans are always criticizing the ideas and practicality of socialism and government control of the economy, yet not one republican president has ever reduced government spending. In short, no matter who you vote for, you are voting for more government control and less freedom - the only difference is the flavor of rhetoric you hear.
I do agree with what you are saying. However, I question why people don't ask the candidates when they ask for votes and later when they are in their seats after winning. In any democratic setup, the government is answerable to the people who had chosen them. Now it's up to the people whether they are willing to raise their voices or to sit and bear the consequences.
