The only GOP fall back Plan "B" is to let Obama take us over the cliff, watch the recession unfold, watch the military get destroyed, and then hope that when the debt ceiling expires in mid February they can rally the public to their side and refuse to raise it without real Entitlement reform.
That's probably a loser as well.
Too many people taking Entitlements, and not enough pulling the wagon to make it go faster.
Obama's approach is to whip the horses that are pulling wagon even harder, until they bleed. This is NOT about tax revenue for him, it is about hurting "rich whitey" and making everyone poorer. I am 100% convinced of that.
