Real power is not a commodity, it is consent. Specifically, consent from large groups of people. Power can only be bought when people consent to being bought off, and it can only be stolen when people consent to giving it up through some form of intimidation. But there is a difference between active consent and apathetic consent. Active consent produces real, tangible power that can move mountains and change the wheel. Apathetic consent produces the shadow of power, people go along with it, but their hearts aren't in it. Consent to the activities and policies of politicians fall into the second category. Only half the population is motivated to spend one hour or less to do something as easy as voting, now that is apathetic consent to be governed.
I am reminded of a story about FDR. During the early days of his administration, he met with labor leaders, they gave a presentation to try to convince him to adopt their policies. At the end, FDR told them that they had convinced him and he completely agreed with what they were saying, and that now they had to go out into the public arena and force him to do it. Hating politicians for being spineless and unable to do what we want is like hating grass for being unable to remain rigid against the wind. If we want to shift the way the grass bends, we have to change the direction of the wind.
I don't bother getting angry at politicians anymore. Not worth the effort, they just do what they do and that won't change until we change our system of government. Getting some active consent going for a policy will change policy, but it will not change the anti-participatory nature of our republic.
It seems to me that too many people on the left focus on the people at the top levels of our government, and focus on them for failing to live up to America's ideals. But they don't have the real power. The population that apathetically consents to their existence has the REAL power, and they nullify it by being apathetic. If we ever want to change our society, we have to change the minds of the population and get them organized and acting. Politicians are a moot point, when the population's minds are changed, the minds of politicians will be changed. Just look at the environmental movement's success in converting the general population. Even Republicans are now trying to appeal to green-minded voters. We shouldn't waste our emotional energies decrying politicians and fighting the power-structures unless these activities are aimed at changing people's minds and mobilizing them. And unfortunately, they often are not aimed at this, they are aimed at forcing authority figures to do what we want.
