The thing is, to return our country to a normal two-party system we need to start by recognizing that GOP no longer resembles an American political party.
In organization it is much more like a modern army at war. Its declared enemy is just one man, President Barack Obama. One in the Supreme Court, reliably churning out new law (with that one amazing exception) to It has powerful allies, not least the Gang of Four Plus speed the GOP’s conquests and fund its campaigns. It requires its front-line troops in Congress to sign a pledge never under any circumstances to vote for any tax increase, thus making compromise impossible. It destroys unions where it can — as in Wisconsin — and chips away at their power wherever they have any. And it flexes its political muscle in arenas generally thought of as nonpartisan, such as school boards, library boards and so on.
Unfortunately for the world we live in, ceding so much power to a political party means that that party has an inescapable obligation to conduct itself in ways beneficial to the general good. Unfortunately the Republican Party is enslaved to the interests of fossil fuels. They cannot resist the tragical changes in our world’s weather, since it is that burning which causes them.
The only hope for the world is to terminate their control of the forces which are dooming us to worsening storms, droughts and spoilage of our natural resources. That is not arguable. It is a fact of our lives which we have lived with for steadily worsening conditions for generations, and can’t afford to let go on.
