When they're in the Whitehouse, there's not much you can do, especially when the political machine of the Corporate Party won't allow anyone but their own handpicked puppets to become president.
Obama, for instance, swore to protect the Constitution of the United States, but has repeatedly shredded it and our Bill of Rights. He has also bypassed Congress with signing statements (something he said he wouldn't use). He promised to pull us out of Iraq on the first day (that we could "take that to the bank"), but he dragged his feat for years. Now, we're still in Iraq, even though they've changed the name of our "occupation." And Obama had the criminal audacity to say that those who were imprisoned in Guantanamo should stay there indefinitely, even if found innocent of all charges!
I can't believe people still trust that treasonous criminal. Heck, I voted for him in 2008. I naively believed his rhetoric. Then I woke up.
Perhaps the best way to deal with such duplicity is to walk away. Stop buying corporate goods. Stop buying gasoline, as much as possible. Drive a stake in the heart of the corrupt beast by not feeding it with our dollars. Buy local. Buy fresh produce -- nothing packaged (it's all poisonous, anyway, giving America highest cancer rates). Bank locally. Boycott Bank of America, Kelloggs, Exxon, etc. Stop watching TV. Each one of these monsters is owned by a handful of companies, which in turn is owned by a handful of companies, which is owned by a small clique of psychopathic elite who don't care about America or mere millionaires.
Stop going to allopathic M.D.'s and stop taking Big Pharma poisons. They don't know what they're doing, or they know, but don't care. Profit is their game. Curing is anathema to them. They're into "disease maintenance," not "health maintenance." That kind of duplicity is what led to the outlawing of cures. The revolving door between government and corporations has fed this monster.
