The Democrats, like their leader, are anxious to plunge over the cliff. Their coconspirators, the media have painted the GOP as the villains who only want to protect the “rich”. Going over the cliff entails massive tax increases and drastic cuts in military spending. Any spending cuts they don’t want can be rather easily restored after the media runs “news” stories about the suffering and anguish of the poor, the unemployed, and the elderly. The minorities will blame Republicans and will be thankful the Democrats restore their entitlements.
By mid year the Republican Party will be even more irrelevant and the Tea Party declared a terrorist group.
Any House proposal made in 2013 can make the tax cuts retroactive. The fiscal cliff blow might be bad but won’t be fatal, as long as a fix is made in time.
