Unfortunately, Boehner has strayed too far in Obama's direction just to get a deal. That is why individual Republican Congressmen can not go along with him.
Now, the Fiscal Cliff is the least harmful option, and it will be destructive. Obama's "Plan" would demolish our economy. A Boehner "compromise" would be between harming the economy (Fiscal CLiff) and demolishing the economy (Obama Plan).
Looks like we're going over the Cliff, and all is Obama's fault.
